What is the power consumption in an inductive circuit?

In a purely inductive circuit, power consumed = Q = VIsin φ. In inductive circuit (having both R and L) power is consumed by resistor R which is P = VI cos φ.

What will be the power in a pure inductive circuit?

Why Power in Pure Inductive Circuit is Zero (0). We know that in pure inductive circuit, current is lagging by 90 degree from voltage (in other words, Voltage is leading 90° from current) i.e the phase difference between current and voltage is 90 degrees.

Why power is consumed by pure inductive circuit is zero?

In a pure inductive circuit, instantaneous power may be positive or negative. Because instantaneous power is the product of the instantaneous voltage and the instantaneous current (p=ie), the power equals zero whenever the instantaneous current or voltage is zero.

What is power consumed in a pure resistor?

Therefore, since the voltage and current are in phase for a purely resistive circuit, its PF is 1. With pure inductive or pure capacitive circuits, the current is 90o out of phase with the circuit voltage; thus, the cos φ = 90o. Hence, the PF of these circuits is zero.

How much power is consumed in a pure inductor pure capacitor when connected to AC source?

Answer Expert Verified No real power is consumed on an average during a cycle in a pure inductive or pure capacitive AC circuit. During one part of the cycle, inductance stores energy coming in through the current, and during another part of the cycle inductance releases energy back to the circuit.

What is the power consumption in a purely inductive and capacitive circuit?

Thus, the pure inductive circuit consumes zero active power and it consumes reactive power only from the supply source. In a pure capacitive circuit the current leads the voltage by 90° because the capacitive load always opposes the rate of change of voltage.

How much power is consumed in a purely inductive and purely capacitive AC circuit?

Answer Expert Verified. No real power is consumed on an average during a cycle in a pure inductive or pure capacitive AC circuit. During one part of the cycle, inductance stores energy coming in through the current, and during another part of the cycle inductance releases energy back to the circuit.

Why pure inductive and pure capacitive circuit is zero?

The active power drawn by a pure inductive and a pure capacitive circuit is zero.In a pure inductive circuit the current lags the voltage by 90° because the inductive load always opposes the rate of change of current. The power factor of the purely inductive circuit is zero(lagging).

What are the power consumed in a purely resistive circuit?

In a purely resistive circuit, the current and voltage are both in-phase and all the electrical power is consumed by the resistance, usually as heat. As a result, none of the electrical power is returned back to the source supply or circuit.

What is power loss in an ac circuit containing pure inductor?

Power loss is zero in case of pure inductor.

Does capacitor consume power?

If you charge a capacitor, it will slowly lose its charge due to its internal resistance. The capacitor therefore consumes energy, but in practice it is negligible. Ideal capacitor does not consume energy. The capacitor will heat up if it is not properly sized according to the circuit requirements.
