Parallel Inductance

When several inductors are linked across the same voltage source to generate parallel branches, this configuration is known as parallel inductance in electrical circuits.
In the parallel configuration, every inductor has the same voltage across its terminals, but the currents they carry vary according to their unique properties and impedance.

The fundamental goal of employing parallel inductance is to modify the circuit’s total inductance value while preserving the voltage across each inductor.
By enabling the use of various inductor values to produce desired impedance characteristics and frequency responses, parallel inductors provide circuit designers with design flexibility.

Understanding Parallel Inductance:

Here are some key applications of parallel inductors:

Impedance matching: Parallel inductors play a crucial role in impedance matching, a vital aspect for optimizing signal transmission or power transfer in radio antennas.

Power supply filters: In power systems, employing multiple inductors in parallel aids in the filtration of high-frequency noise, thus enhancing operational efficiency.

Resonant circuits: Parallel arrangements are integral components within resonant or tuned circuits, employed across various fields such as radio frequency adjustment and medical diagnostic imaging.

Some key differences between parallel and series inductors are:

Current flow:”In circuits with parallel inductors, electrical current may fluctuate among various branches, whereas in circuits with series inductors, the current remains consistent across all inductors.”

Voltage drop: In parallel inductor circuits, the voltage drop remains consistent across all inductors, contrasting with series inductor circuits where the voltage drop may differ for each inductor.

Total inductance: The combined inductance of inductors connected in parallel decreases, while the combined inductance of inductors connected in series increases.

Note: When constant current flows through the inductor, there is no change in the current flowing through the circuit.
