Density of ice less than water

 An analogy can be drawn between the formulae related to a capacitor and inductor. Observe the similarity in various quantities that are related to the two.

Example:

To obtain a displacement current of 1 A across the plates of a 2 µF capacitor, the voltage across it should be varied at the rate of



Answer:

The expression for displacement current through a capacitor is



Here, C is the capacitance and  is rate of change of capacitor voltage.

Substitute the known values.
