Question

two resistors of resistance 20 ohm and 30 ohm are joined in parallel . a potential difference of 15 v is applied across combination . find the power consumed by 20 ohm?

Answer 1

Answer:

I hope you have got your answer so mark me brilliansit and follow me ❣️

Explanation:

20 and 30 ohms connected in parallel

Resultant is 1/20 +1/30=5/60=1/12=12ohms

Total resistance is 8+12=20 ohms

Current is 12/20 amps

voltage drop across 12 ohms is 12*12/20=144/20=7.2 volts

Current in 20 ohms resistor is 7.2/20=0.36amps
