The size of a capacitor affects how much charge it can store (its capacitance), its voltage rating, and its physical ...

Editor's Note: Here's another take on the transformerless AC line power supply, which finds use in some well-insulated, low-power devices. Our technical reviewer pointed out that C ac should be an ...

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 ...

This Idea For Design shows how a gyrator circuit can be used to perform certain ac tests on units under test that require a dc-current feed. Designers have long used the gyrator circuit to create a ...

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 what capacitors are and how they store and release electrical energy in electronic circuits. Capacitors are passive components that manage voltage, smooth power delivery, and ...
