Answer

$25 \, \Omega$

Here are the solutions to the questions.

2.1 Calculations

Given: Resistance of coil ( $R$ ) = $25 \, \Omega$ Inductance of coil ( $L$ ) = $0.2 \, \text{H}$ Supply voltage ( $V$ ) = $20 \, \text{V}$ Supply frequency ( $f$ ) = $5 \, kHz = 5000 \, \text{Hz}$

First, calculate the angular frequency ( $\omega$ ) and inductive reactance ( $X_L$ ). $\omega = 2\pi f = 2\pi (5000 \, Hz) = 10000\pi \, rad/s$
