Basic Electricity – Power and watts
Basic Electricity – Power and watts
A tutorial on electrical power and watts. A practical example of light bulb power measurement is shown as well as a demo how to calculate appropriate resistor sizes.

understanding in a very simple way. thanks
YOou and Paul at Learnelectronics are very inspirational.
BEST TEACHER EVER
Lovely videos… With practical examples and good explanation
Good information. Thank you.
Thank u so much. ……v clear
wow great explanation
how a light bulb can "draw" something? in this case current (electrons per second)? a higher wattage light bulb has a filament with a lower electrical
resistance? edit: 2:26 —> why through the light bulb flows fewer amps at a higher voltage than the led setup which has a lower difference in potential energy but through which flows more amperes?
Flicks light switch….don’t try this at home kids
thx you very much
Excellent series of lectures for beginners in electronics. Highly recommended. I hope there will be more to come.
Thanks. It was really helpful..
Thank you for the practice!
Hey 137×0.02 = 2.74W this almos same 2.76W only 0.02W diferenc
Sorry for my bad english
I think you need clearer explanation for the 120V AC (I believe this is RMS voltage) driving light bulb compared to LED requiring DC.
I have a question
If we are using 60watt bulb in 220v then amphere is very low but the normal home wire electricity will give more than that how the bulb work in high amphere
This is straightforward.
Helped me a lot, Great Video!
KEEP ON MAKING VIDEOS PLEASE
Can u please guide me to calculate the time when 48v 2kw motor is connected to 48v 100ah battery.
why and the heck don’t they just use one word for one thing amps, current. I, Joules, combabiyas… what the… to damn confusing..
Great job explaining.
turn down for "watt"
why electricity is transmitted at high voltage ?
Is it possible to boost 100watt to 250 watts like boosting voltage
thanks for the explanation
4:40 Damn right, just check out ElectroBoom’s recent channel explosion
love your videos!
thanks a lot!!
love your videos please recommend a good app for the resistors calculator thanks
Fullllllllll bridgeeee rectifaaayaaah!!!
Man these electricity basics videos are soo useful to me. Thank you
I have a question.
So the power converted into heat on the resistor is called heat dissipation?
How do we calculate the power converted into heat & light in the light bulb? Do we use 3 Volts in the equation?
thanks bro.. the best channel !
Question: Can a person who has ZERO ground in a house, ground just ONE power outlet in the house by running a ground wire from the ground terminal out into a grounded stake in the ground? My house has old screw in fuses, and absolutely no ground wire anywhere. There’s no plumbing or anything in the house to use for a ground either. I run a compost toilet/outhouse, and haul water there. I want to avoid the risk of frying my electronics but I cannot afford a full electrical update. It’s 10,000-12,000 to do this (almost as much as I PAID for the house!!)… I won’t be able to afford it for YEARS best case. SO what I want to do, is somehow protect my electronics by at least grounding ONE outlet cheaply. Is this possible? AND NO, I DO NOT HAVE INSURANCE, so I don’t care if things are certified insurable, just so long as my gear is safe.
Thanks a lot for all the tutorials 🙂
can u be our physics teacher at my school? !!
Still do but understand… So angry, so stupid…
Good video, well educated indeed
My resistor’s power rating is over 9!
How much time electrons takes to transfer the energy, as you have said increasing voltage will increase the transferred energy, i think its speed of light at which energy is transferred.
I like how you encourage the viewers to build stuff from the beginning. Not just theories, like school bullshit.
Okay, I’ve got that down – I’ll be moving up to big boy pants shortly. 🙂
You are the best teacher one needs to have,for explaining these stuffs. Thankyou
I feel like i’m never gonna understand this stuff, and I so want to!
This might be a stupid question but I’ll ask it anyway…
Why won’t electrons flow the opposite way if connecting the battery the wrong way, ending in the same result?
thank u sir 🙂
