How Coils Control Electricity in Every Circuit? Posted: June 13, 2025 | Last updated: June 13, 2025 Inductors are everywhere, from power supplies and filters to transformers and even your smartphone.

Abstract: Current-controlled variable inductors adjust the inductance of an alternating current (ac) coil by applying a controlled dc current to saturate the iron cores of the ac coil. The controlled ...

The value of the variable capacitor is adjusted to 20pF because variable capacitors with this value are readily available. The coil used in the circuit is a simple air core inductor made with 4 turns ...
