Question

Two tungsten bulbs of wattage 100W and 60W power work on 220V potential difference. If they are connected in parallel how much current will flow in the main conductor?
ANSWER IT WITH STEPS ONLY.

WRONG ANSWERS WILL BE REPORTED.

Answer 1

we know that

Power(P) =Voltage(V) ×Current(I)

so,

I=P/V

Here I1 =100/220  ,n  I2 = 60/220

Since, these are in parallel the voltage is the same over both bulbs and there is only a resistance

so, we have

I total= 160/220 =0.728A
