To solve the problem, we will use the information provided for both the DC and AC circuits to find the resistance and inductance of the coil. ### Step 1: Calculate the Resistance (R) of the Coil When a DC voltage of 100V is applied, the current flowing through the coil is 1A. We can use Ohm's Law to find the resistance: \[ V = I \cdot R ...
