Question

A $3.56 H$ inductor is placed in series with a $12.8 Ω$ resistor. An emf of $3.24 V$ is then suddenly applied across the $R L$ combination. At $0.278 s$ at which rate is energy appearing as thermal energy in the resistor (in $m W$ )?

Open in App

Solution

Hence, Power in the resistor (in mW)= 328 mW.
