Calculate the current in the 240-Ώ filament of a bulb connected to a 120-V line.

Question

Power = IV

Answer 1

so what if P = EI?
I = E/R = 120/240 = ...

Answer 2

so what if P = EI?
I = E/R = 120/240 = ..

current =voltage/resistance = 120v/240 ohms = 0.5A

Not sure if it is correct but trying to understand it

Answer 3

you are correct.

Answer 4

thank you for your help
