Test: Mechanical Analogy of an Inductive Circuit - Electrical Engineering (EE) MCQ

The current in an inductive circuit is maximum when there is no voltage applied because the coils of the inductor store electric flux.

The current in an inductive circuit is zero or minimum when the value of the applied voltage is maximum.

In a pure inductive circuit the voltage leads the current and the current lags the voltage by a phase difference of 90 degrees.

In a pure inductive circuit the voltage leads the current and the current lags the voltage by a phase difference of 90 degrees.

The inductor does not allow sudden changes in current because if current changes in the inductor occurs in zero time, the voltage becomes zero which is not possible.

Inductance is inversely proportional to current since, as the inductance increases, current decreases.

In a pure inductive circuit, current is lagging by 90 degrees from the voltage. The power factor is the cosine of the angle in between the voltage and the current. If the angle between the voltage and current is 90, then cos90=0. Hence, the power factor is zero.

The power in a pure inductive circuit is zero because the phase angle is zero, due to which the power factor is zero and hence the power is zero.

Inductive reactance is nothing but the impedance. Impedance is the AC equivalent of resistance, hence the unit for inductive reactance is ohm.

The average current is the average of the current which flows in the inductor. Hence it is I/2.
