To solve the problem step by step, we will analyze the situation with both the DC and AC sources, and then calculate the inductance of the solenoid. ### Step 1: Analyze the DC Circuit We know that when the solenoid is connected to a 12 V DC source, the current flowing through it is 2 A. Using Ohm's Law: \[ R = \frac{V}{I} \] Where: ...
