What happens when you connect a charged capacitor to an inductor? You get an oscillating circuit. Here's how it all works.

We've talked about how AC circuits change voltage, but let's take a deeper look.

Sources of inductance. An inductor consists of a coil of wire wound around an iron or non-magnetic (air) core. Current passing through the inductor establishes a magnetic flux. The resulting magnetic ...

Active inductors have emerged as a transformative component in CMOS radio frequency (RF) circuit design, effectively replacing traditional passive inductors with active semiconductor networks.

SMPS circuits offer an efficient way to reduce AC from a mains source to any desired level for powering low-voltage circuits, though this comes at the cost of components such as control ICs, switching ...

The inductor continuously flies between these two sets of connections (current buildup through the transistors and current decay through D1 and D2) as the circuit oscillates.
