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 ...

Capacitors behave differently than resistors, where resistors allow a flow of electrons through them directly proportional to the voltage drop, and capacitors oppose changes in voltage by drawing or ...

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 ...

This video explains how capacitors work and why they are essential in modern electronics. Capacitors store and release ...

Inductance is the link between electric circuits and magnetic fields. Voltage and current sine waves are in-phase when they peak and cross the zero axis at the same time. However, this rarely happens ...
