Question

one lamp rated 100w-220v and a tv set rated 250w-220v are connected in parallel to main electric supply. calculate the current drawn from main supply

Answer 1

Answer:

Answer : The current drawn from the supply is 0.45 A.

Explanation :

It is given that,

Power of the lamp, P = 100 W

Voltage, V = 220 V

We know that the power of electrical appliance is given by :

P=V\ IP=V I

I is the drawn current from the supply

I=\dfrac{P}{V}I=

V

P

I=\dfrac{100\ W}{220\ V}I=

220 V

100 W

I=0.45\ AI=0.45 A

Hence, this is the required solution
