Question

PROVIDE COMPLETE AND DETAILED SOLUTION

Answer 1

Explanation:

I1=P1/V=100/220=0.45 A

I2=P2/V=60/220=0.27 A

I=0.45+0.27=0.72 A

Answer 2

Explanation:

There are 2 loads(bulbs) and are in parallel with voltage source.

>>same voltage with be seen across both loads(bulbs) as they are in parallel with source.

=220v=V1=V2

>>As they are in parallel current division will happen.

Given currents i1 and i2.

>>Given power for each load

Power=V×I

.

. . P1=V1×i1. P2=V2×i2

100W=220v×i1. 60=220×i2

i1=0.45A. i2=0.27A
