Question

two resistor of resistance of 10 ohms and 20 ohms are connected in parallel. A battery supplies a current of 6A to the combination. Calculate the current in each of the resistor and power of each resistor.​

Answer 1

The circuit current

I = 12/(10+20)

I = 12/30

I =0.4 Amps.

Power dissiparion in 10- ohm resistor

P1= I^2R1

P1 = 0.4 x0. 4 x10

P1= 1.6 watts

Power dissiparion in 20- ohm resistor

P2= I^2R2

P2 = 0.4 x0. 4 x20

P2= 3.2 watts
