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 ...
This video explains the function of inductors and how they store energy in a magnetic field when current flows through them. Inductors are essential passive components used to manage current changes ...
This video explains what capacitors are and how they store and release electrical energy in electronic circuits. Capacitors ...
Energy meters, HVAC (heating/ventilation/air-conditioning) systems,and high-power equipment thatruns on three-phase ac inputs pose achallenge to power-supply ...
Power relays are specifically designed to handle either AC or DC. It’s important to know the fundamental differences between them before building them into a system. Introduction to AC and DC Power ...
1895: Charles Proteus Steinmetz receives a patent for a "system of distribution by alternating currents." His engineering work makes it practical to build a widespread power grid for use in lighting ...
UofG engineers are teaming up with industry to develop environmentally-friendly, biodegradable circuit boards for use in ...
