Question

Two lamps, one rated 100 w; 220 v, and the other 60 w; 220 v, are connected in parallel to electric mains supply. Find the current drawn by two bulbs from the line, if the supply voltage is 220v.

Answer 1

Here is the answer for your question with steps.

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
