Chapter 23.1, Problem 9PP

To determine

To explain: the reason why the resistor with the lower resistance will operate at a lower temperature.

Explanation of Solution

Introduction:

Power is given by $P=I^{2}R$ .

Here, $I$ and $R$ are current and resistance respectively.

Power is proportional to the resistance. That is, as resistance decreases, the power dissipated will also decrease. Due to low power dissipation, the resistor with low resistance will be cooler.

Conclusion:

Hence, the resistor with the lower resistance will operate at a lower temperature.
