This video explains what capacitors are and how they store and release electrical energy in electronic circuits. Capacitors ...

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 ...

Alternating current circuits improve the versatility and usefulness of electric power systems. In the late 1800s, Nikola Tesla demonstrated phenomena with alternating current (AC) electricity that ...

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 ...

As the story goes, the rock band AC/DC took its name from a label on an old sewing machine in the Young brothers’ home. It must have meant that the machine could run on either alternating-current or ...

When choosing a switch to use in an electrical design project, there is a perception that it is possible to use any switch, provided its current rating is greater than the maximum load in the circuit.

You can't live without your smart phone charger. I understand that. However, the charger needs a DC supply. DC stands for Direct Current (this means that you can't say "DC Current" - that would be ...

This video explains what capacitors are and how they function as energy-storing components in electronic systems. Capacitors temporarily hold electrical energy and help manage voltage and signal flow ...
