To find the potential difference across a solenoid, we can use the formula: V = L dI/dt

where V is the potential difference, L is the inductance of the solenoid, and dI/dt is the rate of change of current.

Given, a constant current of 2A is passing through a solenoid of inductance 12H.

Since the current is constant, dI/dt = 0.

Therefore, the potential difference across the solenoid is: V = L dI/dt = 12 x 0 = 0 volts

Hence, the potential difference across the solenoid is 0 volts. This is because there is no rate of change of current, so there is no induced EMF across the solenoid.
