Alternating current (ac) or direct current (dc) circuits are capable of carrying very different currents, as illustrated by the ratings on the switch in Figure 1. This is why it’s so important for ...

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 ...

The battery as we know it today was an invention of Italian chemist and physicist Alessandro Volta. He witnessed electricity splitting water into its constituent elements of oxygen and hydrogen and ...

For motor applications, engineers have several options at their disposal. Typically, engineers can choose between direct-current (DC) or alternating-current (AC) motors. Machine Design has covered the ...

A semiconductor diode is an electronic component that allows current to flow in only one direction, acting like a one-way valve for electricity. It is commonly used for voltage regulation, converting ...
