An "ohm" (symbol: Ω) is a unit of electrical resistance in the International System of Units (SI). It measures how much a component or material resists the flow of electric current. One ohm is defined as the resistance of a conductor in which a current of one ampere flows when a voltage of one volt is applied. The concept of ohms is fundamental in Ohm's Law, which states that voltage (V) equals current (I) times resistance (R): V = I × R V=I×R. Edit: I type this for 1 sec
This is all well and good, but current is the flow of electrons and electrons flow from positive to negative in a battery (DC) so in the circuit they flow from negative to positive
Voltage is usually constant which reflects a difference between two points but current and resistance are inversely proportional. Increase resistance, decrease amps and vice versa.
Draw a triangle. Inside on the top, put an E for voltage. Under that on the left put I for current. On the right, put R for resistance. To find an answer, just cover the one you want to know, and that is your equation. To find E multiply I times R. To find I divide E by R.
I'm a newbie to the electrical world. So if Ohms law states "the higher the number amps, the greater the amount of volts" How are high current low voltage situations possible?
It all depends on the current. You can have high current low voltage situations depending on the resistance - if the resistance is too high, you can have a small amount of current flowing through the circuit with a high potential difference (volts). For example, in power lines, you have a high voltage but very low current flows through the lines.
@@Scienceabc Thanks for the response, electricity is confusing especially when learning. 🤣 If I remember correctly, the higher voltage is needed / used to allow for the long distance power transmission?
E=I×R I=E/R R=I/E Super confusing at first.. I just co vert it over to VAR so I can keep track of what I'm doing instead of changing terminology and confusing myself
@@caunt.official Almost every power source is more or less constant voltage batteries included. Some lab bench power supplys have constant current modes
Bad example - incandescent light bulbs do not follow Ohm's law. Neither do electrolytes, semiconductors or gas discharge tubes. Only metals follow it and at low current densities too.
Everything follows ohm's law. The different things you said just don't have constant resistances so you cant predict them in different conditions using ohms law
@@laserdiode Everything does not follow Ohm's Law, even metals don't follow it at high current densities. Metals also change resistance with different conditions e.g. temperature.
In every single case ohms law holds. There is no way it wouldn't hold because resistance is literally defined to be voltage drop dividend by the current. If you use ohms law to predict the voltage and the current in different conditions you always assume that the resistance stays the same. If you do that to a light bulb and get an incorrect answer it doesn't mean that ohms law was wrong but that your assumptions were wrong

Students across the world have access to the goldmine of such educational content out there which previous generations didn't had.
i was just thinking this... i studied electrical engineering 20+ years ago... no youtube... had to read the textbooks and listen to poor lectures.
And do they use it? Nope. Not many. Check a university lecture playlist: vid1 (500views), vid2 (250views), ... vid10 (100views).
Now the knowledge is free out there so does entertainment and comfort. What makes the difference is how one spends their time.

Oh my god understood .....thank God I understood finally😅😅
👍
Thanks, good visual, good explanation. Short & concise. Well done
Glad it was helpful!
thank you a lot! amazing comparison with water pipes:3
Glad you liked it!
For real ❤
This is all well and good, but current is the flow of electrons and electrons flow from positive to negative in a battery (DC) so in the circuit they flow from negative to positive
Thanks for the clarification
Thanks
Question here, if the pipe of water had no pipe on one end but water was flowing out, would that part then be 0 ohms?
Explain how to do this 😮
Sooo, volts and like PSI, and amps are like GPM?
I never understood what ohms law was thanks
Isn't the diameter of the pipe more analogous to electrical resisitance than "friction of the pipe"?
The more I grow up the more science and magic sound similar
Magic is actually a misunderstood science from decades and millennia ago. I do not know the definition of magic today.
current is rate at which charge flows w.r.t time. I= Q (charge)/Time. Voltage is Energy/Charge.
Very good explained ...
Thanks and welcome
It's mind blowing🎉❤😂
Wrong electrone moves (-) to (+) not (+) to (-) side
Please tell me what is importance of i=v/r and p=ei

what about wattage ?
Volts x amps = watts
❤ Nice
Thanks 🤗
Image showed 20 amps and 19 voltage...
P=UI²
Isn’t it E for volts not v ?
E=I×R
I=E/R
R=I/E

The higher number of amps the greater number of voltage
If Voltage is Current * Resistance, then why in my breadboard voltage doesn’t change after resistor?
Because you have a constant voltage supply so only the current changes. If you had constant current source the voltage would change.
@@laserdiode how do I know if my power supply is constant voltage or constant current? How about li ion batteries?
@@caunt.official Almost every power source is more or less constant voltage batteries included. Some lab bench power supplys have constant current modes
Ohm was a plumber 😎
is the higher the number in amps than voltage because energy is lost through the friction aka ohms when it’s traveling?
Thank you ❤🎉😢
You got volts and amps the wrong way around with the water example. Amps are the current not Volts.
First comment after exam 😂😂😂
That was good until the last statement, which left me with a worse understanding
than prior to the video
