Question

calculate the current passing through a bulb rated 60W,240V when it is connected to a 240 V power supply.
help!!!!!!!!!

Answer 1

P=VI
60=240I
I=.25 amp

Answer 2

We know that V=IR

V= voltage or potential difference

I= Current

R= Resistance

Multiplying both sides by I, we get

VI=I × IR

P=I x V. (Power = voltage x current, V=IR)

So I= P/V= (60/240) W= 0.25 A
