Question

please please help me fast

Answer 1

R1 = 10 + 20 = 30

R2 = 15 + 30 = 45

Now R1 and R2 are in parallel and Voltage in parallel is same.

I1 = V/R1

= 12/30 = 2/5A

Now in R1 10 and 20 are in series so current in series is always same.

Current across 20 ohm is 2/5 A


I2 = V/R2

= 12/45

= 4/15

In R2 15 and 30 are in series so current will be same

Current across 30 ohm is 4/15 A

Thanks
