Power factor correction uses parallel connected capacitors to oppose the effects of inductive elements and reduce the phase shift between the voltage and current. Power factor correction is a ...

Power factor (pf) is the ratio between real power (P) flowing to the load, and the apparent power (S) in the circuit: pf = P/S. It is a sinusoidal waveform and therefore expressed as a dimensionless ...

You've seen it pretty much every day now for decades, and you've interacted with it just as many times, but have you ever wondered why the power symbol looks the way that it does? There's a joke that ...
