Series and Parallel Circuits - Light Bulb Brightness
ฝัง
- เผยแพร่เมื่อ 12 ก.ย. 2024
- This video discusses the brightness of 3 light bulbs in a series circuit and in a parallel circuit. Each light bulb acts as a resistor; therefore, you can use ohm's law to calculate the amount of current flowing through each identical light bulb.

Lol he is AI!!!!
This is a brilliant concretization of an abstract concept such as electri city ..keep it up
THANK YOU...I'm in Gr8 and I was having some problems understanding why the bulbs shone differently in the to circuts,but this helped alot(i only needed the video until he stopped showing the circuts)
Buddy, u r now probably at highschool🎉🎉🎉🎉
no music pls
If anyone wants to see him, check 3:43 of this video, you can see his reflection on the battery. He had worn a black shirt or may be hoodie and was walking here and there and explaining the concept.
I mean he revealed his reflection for the first time unknowingly.

I enjoyed this demonstration quite well. It helps to visualize things! You don't need the music though; it is rather distracting....Now onward to your magnetic sensors demonstration! 💯💯💯💯💯
This man knows everything
My guy didnt even show a finger😞
Bro, who are u
He is the guy who gives you knowledge

Daymn bro what's going with da music in background boo dis liiiit😂🔥🔥
very good ,but can you lower the music or take it out
You may have an attention issue, the video is near perfect.
Good job. This was great and very helpful. Thank you 😊
9v does not =3v. If you burn out and
Low voltage leds on a high voltage batteries, leds will burn out wild somtimes. I took tons of videos a while ago of that happening. It was so awesome to see
I like the diagrams, It really helps
I am thankful to you for your demonstration . It helped me. Again,thanks a lot

I knew it, he was a disembodied voice this entire time.
Hi, I really love your videos! Would you be able to make one about rolling without slipping? It’s on the physics C exam and it’s one of the few physics topics you don’t have a video about yet

Noob hi 😂 boat noob
For anyone confused on if the light bulb brightness in the series of 2 bulbs is reduced by a reduction in current or voltage, the answer is both.
Here's how:
If we have a circuit with a single light bulb of 2 ohms and a voltage from the battery of 8V:
V= IR
I= V/R
I= 8/2 = 4A going from the battery, through the single bulb, back to the battery
Power generated by battery = power delivered to bulb
Power = VI
P = (8V)(4A) = 32 W absorbed by the light bulb
Now if its the same circuit of 8V from the battery but going across 2 of the original light bulbs in series, each with 2 ohms of resistance:
V= IR
I= V/R (R is total resistance)
I= 8/4 = 2A going from the battery, through the 2 bulbs, back to the battery
Power delivered to each bulb = VI
Since the voltage across each bulb added together must equal the voltage supplied by the battery, the voltage across each is 4V
P = (4V)(2A) = 8 W absorbed by each light bulb
So if you connect a light bulb of 2 ohms of resistance to a battery of 8V, 32W will be supplied to the light.
If you connect 2 light bulbs in series, each of 2 ohms of resistance to a battery of 8V, 8W will be supplied to each light. (16W total)
This means in the 2 light bulb circuit, each bulb will receive 1/4 the power as the 1 light bulb circuit.
Thanks! This vid. really helped me a lot
His videos helped me to pass my degree at varsity
We’ll explain. Many tech need to watch this video to understand electrical
Thanks it's really helpful
In series, the current actually stays the same. The voltage splits for each resistor, however. But the total voltage, adding those two up, will be the same as the battery's voltage. And it's not increasing any resistance; the total resistance stays the same. but it is split among the two bulbs.
Thanks for brining this up. For anyone reading this, watch "Series resistors" on Khan Academy for a short explanation.
We need an OCT elbow reveal
My friend also tried this experiment with 1000 volts battery.
Now I miss him alot.
@@XKGaming nah, I'm just joking brother😂😂
same man my friend did the same but he slipped and the current went in his balls ):
@@RAM-nm4fo 😂
@@xernosity4554 may Your friend RIP.👍
@@allthings8733 yeah ):
I think in series circuit the curent is the same in each resistor but voltage is not the same. In parallel the voltage is same but current is not the same unless the resistor has same values.
Yes, you're right. In series, current stays the same but voltage does not. Thus the total resistance is the same but the resistance is split amongst the bulb which lowers brightness, not bc resistance increases* or current decreases*
Can you show us how to do a combination circuit and how to solve it
Excellent!
how is the current reduced when its in series?
isnt the amount of current going through each bulb in series the same?
i thought the bulbs were dimmer because of the successive energy (voltage) drops across each bulb.
also, when in series, why is the first bulb not brighter than the rest as all the current and voltage goes through it first.
cheers
I would like to know this answer as well!
According to my understanding, the total current is reduced due to increase in resistance(NB: resistors in series) resulting in less current flow compared to the first connection where there was one resistor. Then the very same less current will be the same across each resistor in series. As for the last question, I would expect that(first bulb should be more brighter than others) as well
@@mohaleexelent9210 yeah I was thinking of this as well.
More resistance means less current, because the voltage is constant that will result in less power, less energy, therfore the bulbs are dimmer.
Came in clutch for my science class
Face reveal plz
Doing custom lighting on my boat, this video was a lifesaver after I got done and nothing happened when I flipped the switch
What what when the face reveal ?!
Thanks
Loving the music
GOOD VERY NICE VIDEO AND WELL EXPLAINED
Please use different music in the future. Otherwise great basic video. I like that you are directly reffering to the mathematical formula.
What happens if the bulbs have different resistances?
If the bulbs have different resistance then the next bulb in the series will glow lesser or be more dimmer than the first one.
What happens if you have a switch connected to each lamp on the parallel circuit and you turned off one lamp?, does the current drop as only two bulbs are illuminated?
ka boom 💥
HAND REVEAL PLS
thank you so much brother! This was so helpful
face reveal?
Knowledge "reveal" is good enough
THE ORGANIC CHEMISTRY TUTOR ,
if a lamp bulb draw .15 amps and another lamp bulb draw .25 amps how do you find the percentage of current draw between the two different lamp bulbs? what is the formula
.15 amp lamp bulb draw less current compared to .25 amp lamp bulb by what percentage?
Nail reveal?
bulbs now i understood to connect in parallel..
but batteries should be connected in series or parallel?
in series
why do yall want him to do a hand reveal so bad i- ;;
Thank you!!!!
very helpful sir... thank you ... as you mentioned at the beginning, 6 v will burn out lightbulb, if when hooked up in series did you run 6v to three batteries ... 2+2+2 ... my apologies for my ignorance ...
Bro is everywhere
I just had a question with parralel resistor lightbulbs, if the ratio of the resistances isnt the same wouldn't that mean the higher resistance bulbs would be dimmer as the split of the current in the parralel is no longer equal?
Please - what v/amp ( little modellers) bulb should be used with a 9 v battery ?
if series circuits have more resistance than parallel circuits, why does bulb glow brighter in parallel?
because higher resistance=higher heat energy produced = more light produced
Why don't you upload chemistry videos anymore?? ☹️😢
You can go back to them
Thank you.... keep going
It was exactly what i was looking for but could not get anywhere else
Thank you so much
Current same in series.
Current split in parallel.
Nice
great job
and thank's
I love you
you saved me
Your videos are so so so helpful thanks tons!
Thank you i learned you more.
From you more*?
More from you*
So when there is 3 bulbs in a parallel circuit is the voltage 1 Volt in each of them but the brightness is the same or each of them it is 3 Volts? I'm so confused please helps someone
if your battery supplies 9 volts each bulb in parallel will have 9 volts. whereas in series each bulb will have 3 volts
@@Felix-sb5wp I thought it has to add up to 9
@@Felix-sb5wp because if it added to 9 then it should be 3
No
I hate how this guy littersllu has solutions to every thing I struggle with in life, besides women
I watched it.
how did he calculate that how much current the battery is dishing out in parallel circuit in the end?
thank you
Hi want to ask..if the parallel circuit i tap the +ve wire from 2nd light bulb to first +ve side light bulb..and -ve wire 2nd light bulb to -ve side light bulb..is it still consider parallel?circuit still working?like yours u tap all +ve and -ve to connector..
What if you have a series circuit that breaks into a parallel circuit?

sir can i still use a resistor on this bulb?
I have flashlight with 4 18650 battery 2series and 2 pararell so how can I connect the 3 PCs xhp70 led one by one in that set up of my flashlight tnx.?
Will multiple light bulbs connected in series light simultaneously, or with a slight delay?
they should light simultaneously, unless you count the milliseconds between them.
Can you create Wi-Fi as simple as that because there was no satellite for bulb to work if the colbat is a resource from the earth can you create Wi-Fi in a simple way that you did this with the bulb I'm just asking
in this video we gonna go over🤣🤣
What is eletic
Current is not limited in series circuits. Are you sure this video is accurate?
if series circuits have more resistance than parallel circuits, why does bulb glow brighter in parallel?
because higher resistance=higher heat energy produced = more light produced
Anyone else get really excited thinking we’d maybe be able to at least see one of his hands??? Lololol😂
Is there a way to wire in series but yet have the bulbs brightness equal to the bulbs wired in parallel?
two batteries maybe
if series circuits have more resistance than parallel circuits, why does bulb glow brighter in parallel?
because higher resistance=higher heat energy produced = more light produced
Because the energy is shared between the bulbs in series whereas in parallel they get equal energy from the battery
Yea, he actually made a mistake there. the total resistance actually stays the same in parallel.
hand or glove reveal something?
What happens to the current when the switch is open?
no current will flow through the circuit until it is closed
