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

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

This shows the same as like pure inductive circuit i.e. in case of pure capacitive circuit, the total power of the circuit would be zero as Cos 90° = 0.

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.

How is a capacitive load like an inductive load?

Like an inductive load capacitive load also consume both active and reactive power. The phase difference between current and voltage consumed by a pure capacitive load is 90 degrees leading. Although the practically pure capacitive load is not available.

What’s the difference between resistive and capacitive load?

Whereas, in case of resistive load both current & voltage becomes zero at same time. Therefore, switching such type of inductive loads is critical. Such type of load also affects the power factor of system heavily. And hence, electricity bill goes up. Capacitive load is similar to that of inductive load.

What kind of load consumes only reactive power?

Load which consumes only reactive power is called as inductive load. And if you look at the voltage and current waveforms of such load, you’ll find that, the voltage & current are out of phase with each other by 90 deg. Now, when I say they out of phase, that means, both the waveforms reaches their peak value at different times.

Why is inductive instead of capacitive power factor preferred?

But, the bottom line is that most pieces of equipment that cause non ideal power factors are motors and these are corrected by capacitors. Why is inductive instead of capacitive power factor preferred? It’s not anyone’s preference, it’s practicality. Thanks for contributing an answer to Electrical Engineering Stack Exchange!
