ANYONE HERE THAT KNOWS ELECTRICITY ?

[DOdoubleG]

So anyone knows electricity ? Tuesday I have an exam and I am so fcuked up, I added a question on Quora, please check it out and let me know if you have any idea

If you seriously don't understand Ohm's law, it's probably for the best that you fail the course now before you end up causing a fire with a poorly designed circuit.

Yes I do .... V = I x R

Good old memories. I do not remember most of the equations though.

The answer is C.
With same potentials a bulb which draws 30 Watts has higher resistance than a bulb which draws 60 W. Less power = higher resistance with same potential.

Ohm's Law. More resistance = Less power

Here's an explanation similar to your question: https://physics.stackexchange.com/q...cent-light-bulb-have-a-lower-resistance-value

S+I+R = SIR

D+E+A+R = DEAR

 

[yuuzokun]

S+I+R = SIR

D+E+A+R = DEAR

Teach me master.

Sometimes when im bored i watch physics videos on various laws used. Some work together, some contradict each other but to get a pure understanding just watch videos you have a whole 4 days to absorb the information.

(D*E*A*R)^2
=
D E A R
E
A
R

Its ohm's law V=RI
