- This physics video tutorial provides a basic introduction into open circuits, closed circuits, and short circuits. An open circuit contains a break in the circuit and does not conduct electricity. The closed circuit is a circuit that conducts an electric current and has a measurable amount of resistance. The short circuit is a closed circuit with almost no resistance which allows a large amount of electricity to flow in the conductor which can be a fire hazard. This video also briefly discusses the purpose of a fuse and a circuit breaker to prevent the formation of a short circuit.

I finally understood the short, open and closed circuits. Every short circuit is a closed circuit, but every closed circuit is not a short circuit, because in closed circuits there is some resistance, and thus the current passage is limited. But short circuits are dangerous, cables can burn 'cause there is no resistance in the circuit. Well done
My teachers failed to make me understand the difference among these things..I now understand.. Thanks a lot
_Yours teacher failed_ *or* _you failed_
@@piratedgamerxd6861 lul
Nimeget kabisa sasa... Thanks
@@piratedgamerxd6861 well he understands it know because of this video so probably his teacher failed
among us
You are a good teacher. Concise and straight to the point. Well done.
A great introduction; I liked especially his explanation of fuses and circuit breakers and his explanation of what makes a short circuit. This lecture was omitted somehow from his electronics playlist - he should include it for sure.
Sir you are an angel. You deliver concepts in a comprehensive manner which makes them easier to understand and grasp. Keep up the good work!
Thankyou for this brother may GOD Bless and Guide you more
New subscriber here ,😬
i love this dude he explain so well

Ya you are right my teacher puts this guy on sreen
I wish that the teacher explained this in our fundamentals class. When we got further in to class, working on superposition, he was say to "replace one power source with a short." I had no idea what he meant by "short." Thank you for this!
Really helped me thank you!
Ideal for what I needed today bud. Thanks.
I see an another video that is not clear......
And this one so easy to understanding......
Thanks for your this video

simple and to the point. thanks
What a simple & beautiful explanation 🎩 🎩 Off.
💢💢💢
Thanks for the explanation, now I know how to use the steps for Norton and thevenin theorem with this explanation of open and short circuit haha
Thx you helped a lot 💯
Agreed! It helped alot!
Good, very good sir
That's was so much helpful. Thank you so much.
amazing explanation thank you !
Omg Thank u so much 🙌🙌🙏🙏
I am a first year engineering student and all your videos help me a lot 🙆🙆
This is literally year 10 science lol
@@mariyah1608 learning has no age. stop making people feel bad you ignorant fuck
@@mariyah1608 these concepts are revisited using calculus in US universities.
Then they give you harder problems then you had in grade 10 obviously.
@@mariyah1608 It's good to revise your knowledge in order to regain the concepts learnt in school, that's the very reason you excel in studies.
Current flows from (+) to( - )
Very Nice information
for advanced level of information on open circuit and short circuit visit #Electricalengineering360
The flow of electrons is termed electron current. Electrons flow from the negative terminal to the positive. Conventional current or simply current, behaves as if positive charge carriers cause current flow. Conventional current flows from the positive terminal to the negative.
Hi there , you really explained very simply. better than any institute and university. thnx
How does a voltage develop across the unconnected end of a single wire connected to one terminal of a battery and the other terminal?
If the battery’s net charge is zero, then for a 12 V battery, one terminal would be at a potential of +6 V with respect to a conductor at infinity, while the other terminal would be at -6 V. At the physical center in the space between the two terminals of the battery, the voltage is zero.
If we then connect a small wire to, say, the positive terminal, a few excess point charges will move onto the wire, and that wire will now be at the same potential as the battery terminal: +6 V. The wire will be surrounded by an e-field, and since the lines of electrostatic flux must always terminate upon charges, the wires must possess an excess surface charge.
In the above we assumed the net charge of the battery was zero. Supposing that the battery had a net charge. Then how would the charges, potentials and voltage be changed?
Before we answer this, it would be instructive to understand Current, the conduction process and Voltage at the fundamental level.
Electrostatics and circuits belong to one science not two as in the following two videos:
i. th-cam.com/video/REsWdd76qxc/w-d-xo.html and
ii. th-cam.com/video/8BQM_xw2Rfo/w-d-xo.html
Returning to our question of the voltage of the single wire connected to one battery terminal, we assume the net charge of the battery was not initially zero. Perhaps someone with rubber-sole shoes carried the battery while walking on a wool carpet or perhaps the battery was charged to -5000 V, and would deliver a tiny spark if touched. In that case one terminal would still be 12 V different than the other terminal, perhaps -5000 V on the positive terminal and -5012 V on the negative.
It is not possible in this brief post to discuss in more detail the process of production of the voltage of the single wire without a detailed discussion of the capacitance and potential of single conductors.
The last frame References in video #1 lists textbook 4 which discusses these topics comprehensively using a unified approach and provides an intuitive understanding of voltage of a single short and long wire with and without a net charge on the battery.
so simply explaned thank you
Thank you!
This guy is a savior
POV 4th year Electrical Engineering student watching this
I'm grateful to be here in that kinda issue I've stuck in for a long time, You're amazing!
please make a video on general chemistry of spectroscopy
Beer-Lambert law, electronic spectroscopy, rotational spectroscopy, vibrational spectroscopy molecular spectroscopy, raman shift with practice problems. I'm struggling through them.
Thank you so much❣️
How to I make a circuit with to motion sensors that trip a light but only the first one tripped will turn on a light ?
Idk
thanks😀
Thanks sir
From india
Thx for the info
Sir,in close &short circuit, both current flows, then how to check which one is short?
Hi, it was great, I was looking for this article.
thank you for the video but does'nt current flow from neg to positive
yes but these styles of diagrams came to be before we knew that, and people just assumed it went from positive to negative, and to this day diagrams are still often drawn this way.
so yes it is wrong but universally we just agree to draw these diagrams backward.
@@bob-859 me studing for test😑
Nope,remember current is just the flow of charge,and charge can be positive or negative,negative charge is brought about by the repulsion of electrons on the negative side of the battery terminal,due to a negative electric field.
While a positive charge is brought about,by the repulsion of protons(positive test charge),from the positive side of the battery terminal,due to a positive electric field.
So in physics we normally use the flow of charge,by convention,which is positive charge,from the positive side of the battery flowing to the negative side of it,instead of the flow of electrons.
I still have a question. If there are 3 switches that are closed, 1 switch that is open, and two bulbs, will the bulbs turn on even when there’s one open?
It depends on the locstion of the open switch
Wow, who would have thought Mark Wahlberg knew so much about electrical currents!
Thnk u
Excellently explained. Thanks.
5 min video > any 1 hour lecture about this
Outstanding
Thanks!
doesn't current flow from negative to positive, since electrons are negatively charged and thus attracted to the positive terminal..
Hi, great video. So would you say that the voltage in a short circuit is 0?
No, Voltage will also be high
It implies that V = EMF provided in the circuit initially.
If he is asking questions like that what makes you think that V=EMF stop trying to sound educated and give simplistic description we are here to learn not pass a vocabulary test
I thought it current moves from negative to the positives
In electron flow theory the electron flows from the negative of the source to the positive.
This video is using conventional or "hole" flow. Meaning the positive charge left behind by the electron leaving moves positive to negative.
So the negative electron moves negative to positive but the positive hole it leaves behind moves the opposite way.
That is electronic current
@@schulerruler .
,
I was taught the same thing too.
Thank you
My teachers ask if there is source voltage in a shorted circuit. What say you? I think there is.
Thank you. God bless you. I wish some of this information was passed on to me while I was still at home living with an electrician, so I didn't have to get it all from you. God is good though. I would have listened, and done nothing with it. I was a good child, and am still a good child of God. God just needs us to have resistance, discernment. It would have been a great help to see an open circuit in a picture, of a real life object.
Thanks a lot sir
No Problem
Wow
Is a fuse or a circuit breaker considered a resistor
For the closed circuit with a resistor, wouldnt the wire the current flows in before the resistor melt or smth, or is there a reason this wont happen
Doesn’t current flow from the negative terminal to the positive terminal ?
true but it is a convention.
Don't forget the switch is always open on the *outside*
if a circuit has an open switch but all the light bulb are lit up is it open or closed?
My thanks
You are the best
Thanks 👍👍
What if it's a variable resistor..?😅

Tq so much🤩
Thx you helped a lot
Me to
Is open circuit can call a circuit?
best explanation thanks
I thought the circuit flows from negative to positive ?
I did too that threw me off
Ok, I am sure you may have figured it out already. But Electron flow is the one that flows from negative to positive. :)
Nathan Koloi is king
Hi. Please may I ask your advice please
My sprinter 4x4 has been diagnosed on the Mercedes computer
With a
" short circuit to ground or open circuit /Open circuit to voltage supply "
They told me to buy 2 new electrical switches that fit on my gearbox
and I've replaced them costing a fortune and I'm still stuck in low wheel drive and the same reading is on their Mercades computer
Firstly that is a cell and not a battery....... Both are different
Doesn't current flow from negative to positive?
but how does voltage carry through an open circuit!! If according to ohms law voltage = IxR and no current flows across and open circuit then how does current still flow?
Open circuit means current is not going in external resistance but it is flowing in the cell circuit
Thanks!!
👍
Nic
ok
Woooooooooooooooooooooooooooooooooooooooooooow
Simple explanation 👌🏽
Can I have a free merch
Mohammad Ahtesam that’s mean well somebody asked for a free merch and he did
What are you talk English sir
No current flowing by definition is not a circuit at all
Ummmm i think not. We can't just make stuff up. I cant just say white is black or black is white lol
You are correct, it is not a circuit, but a name must be given to it for a reference point. If a fuse busts a closed circuit, will you say, "thank goodness that fuse made the closed circuit "not a circuit"? It makes much more sense to give the situation a name within the context in which you are in. What is the opposite of closed? Open. What is an open circuit? Not a circuit.
Let me use your logic again. When something breaks (a computer, car, or tv) and it no longer works, do you seriously call it "not a computer"? "By definition" a computer makes computations, do you seriously intend to call it not a computer? No, that's ridiculous. You would just call it a broken computer. Or in our case, a broken circuit, a.k.a. an open circuit.
This is now bro. Ok i understand its stupid. It should be given another name other name a specific to a type of not circuit lol. Also please i won't destroy bad but dont ever try win something after your 1st sentence is.... YOU ARE CORRECT. Come on man. Ok see you in a month
Still don’t understand... sorry I’m really dumb I’m gonna
Hi
U scrolled
ElLo I’m UnDeR tHe WaTaT pLz HeLp
Hi
voltage flows from negative to positive. one of the first things you learn in DC circuits. please edit. i stopped watching as soon as you said the opposite
yes voltage is from negative to positive, but the world has accept it to be the opposite,so u cannot say he is wrong
many of the experiment and research is based on this direction of flow
voltage? or current? you should've kept watching since you're wrong especially about voltage flow lmao.
Thanks 👌
