The previous tutorials featured resistors in direct current (DC) circuits wherein the voltage and current have been assumed to be of constant polarity, flow and direction. The voltage, current and ...
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 ...
Switching ac power on and off has been a challenge since Edison and others started switching power more than 125 years ago. Now, a solid-state relay (SSR) uses a patented zero-voltage crossing ...
