Question

two lamps one rated 100W at 220V and the other 60W at 220V are connected in parallel find the total current

Answer 1

hi


P1=100 W , V = 220 V , P2= 60 W (GIVEN)

I1 = ? I2 = ?

P1= VI1

. : I1=P1/ V

= 100/220 = 0.46A

SIMILIARLY ,

I2=P2/ V = 60/220

= 0.27A

TOTAL CURRENT (I) = I1 + I2

= 0.46 + 0.27

= 0.73A
