Question

A 10 ohm resistor is connected in parallel across the series combination of 4 ohm and 6 ohm resistors calculate the amount of heat produced per second in 4 ohm resistance of 10 joule heat is produced per second in 10 ohm resistors

Answer 1

Explanation:

Equivalent Resistance(Req)=10ohms

R1=4ohms

R2=6ohms

In series combination

the current (I) following throughout the circuit is same

So, P is directly proportional to R

P1/P2=R1/R2

P2=4W
