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 ...

Previous tutorials have described that resistors may either be connected as a series circuit or a parallel circuit where the currents and voltages are obtained using Ohm’s Law. To produce more complex ...

Electrical components, like motors close motorA device which spins when current flows through it. Motors are used in fans, food processors and many other devices. and lamps close lampA component which ...
