Question

One lamp rated 100 W-220 V and a television set
rated 250 W-220 V are connected in parallel to main
electric supply. Calculate the current drawn from the
main line.
​

Answer 1

Answer:

1.58A

Explanation:

Lamp:

power=potential difference*current

100/220= I

I= 0.45A

Television:

p=v*i

250/220= I

I=1.13 A

total current drawn= I1+I2

= 0.45+1.13

=1.58A
