Question

A bulb is rated 60 watt and 220 volt and another bulb is rated 100 watt and 220 volt are connected in series with power supply of 220 volt.Find the amount of current flow through the circuit.

Answer 1

P = V^2 / R

Here, V = 220V

R1 = 220*220 / 100 = 484Ω

R2 = 220*220 / 60 = 806.66Ω

R2 is greater than R1.

P = I^2 R

I = √220/484

Solve this and you will get the answer.

I Hope It Is Clear For You!!!
