Question

Calculate the heat generated per second in resistor A in the given circuit where there are resistors of 3 ohm,3 ohm,3 ohm,3 ohm and 2 ohm with 16 v battery

Answer 1

Answer:

64/3

Explanation:

As three resistor of 3 ohm each are in parellel to each other which give net resistance =1 (let say it b)

then the resistor A of 3 ohm

equivalent resistance b of 1 ohm

and resistance of 2 ohm

are in series which give net resistance 3+1+2=6ohm

so net current in circuit I=V/R so I=16/6 which is 8/3

now heat through A (of 3 ohm resistance ) by applying H=I*I*R => 8/3*8/3*3= 64/3 J
