How to calculate capacitor bank value to maintain unity power factor with some suitable example?

How to calculate capacitor bank value to maintain unity power factor with some suitable example?
Answer : To calculate the capacitor bank value required to maintain a **unity power factor** (i.e., a power factor of 1) for a load, we need to correct the **lagging power factor** of the system by ... **. This will offset the reactive power consumed by the load, bringing the system's power factor to unity....
