To calculate the inductance of the solenoid, we will follow these steps: ### Step 1: Calculate the Resistance of the Solenoid When the solenoid is connected to a DC source, the voltage (V) is 12V and the current (I) is 2A. We can use Ohm's law to find the resistance (R) of the solenoid. \[ R = \frac{V}{I} = \frac{12V}{2A} = 6 \, \Omega \] ...
