To solve the problem step by step, we will analyze the given information and apply the relevant formulas. ### Step 1: Understand the circuit We have a coil (inductor), a capacitor, and an AC source connected in series. The maximum RMS current observed is 6 A when the RMS voltage is 24 V. This indicates that the circuit is at resonance. ### Step 2: Calculate the resistance of the coil At resonance, the impedance (Z) of the circuit is minimized and is equal to the resistance (R) of the coil. We can use Ohm's law to find the resistance: ...
