Question

Two resistors of resistance ratio 3:4 ara connected in parallel . Compare the magnitude of heat produce in them

Answer 1

Ratio of heat produced in the resistors connected in parallel is - 4:3.

Heat is produced due to power dissipation in the resistors.

Power dissipated for parallel resistors is calculated by the formula -

P = V²/R

Now, for two resistors, since the voltage will be same, the ratio of power dissipated is given below.

P1:P2 = R2/R1

Given in question is R1 = 3 and R2 = 4.

Therefore, P1:P2 = 4:3.

Hence, the power consumed and thus heat generated will be in the ratio 4:3.
