Question

A lamp rated 100 w and 220 V is connected to the main electric supply what current is drawn from the supply line if voltange is 220 v

Answer 1

⚡⚡Hey Friend⚡⚡

P = 100 W
V = 220V

=> P = V*I

=> 100 = 220*I

=> I = 100/220

=> I = 0.46 A

Answer 2

Hello friend___❤

Here is your answer ✒

For the 1st lamp:

Power P1 = 100 W and

Potential difference V = 220 V

Therefore,

I1= P1/ V = 100/220 = 0.455 A

For the 2nd lamp:

Power P2 = 60 W and

Potential difference V = 220 V

Therefore,

I2= P2/ V =60/ 220 = 0.273 A

So, the net current drawn from the supply is given by

= I1 + I2 = 0.455 + 0.273 = 0.728

I hope, this will help you___❤❤

Thank you
