What is inductance meters?

Inductance meters are devices that are used to measure the inductance of an inductor. Inductors are passive electronic components that store energy in a magnetic field when electric current flows through them. The inductance of an inductor, measured in henries (H), is a measure of how much energy the inductor can store.

Inductance meters use a variety of methods to measure the inductance of an inductor. The most common method is to use a bridge circuit, which compares the inductor under test to a known reference inductor. The inductance meter adjusts the frequency and/or amplitude of the test signal until the two inductors are perfectly matched, and then measures the frequency and/or amplitude of the signal to determine the inductance of the unknown inductor.

Other methods for measuring inductance include using an oscillator circuit, measuring the current and voltage across the inductor under test, and using a resonance circuit.

Inductance meters are commonly used in electronics and electrical engineering applications to measure the inductance of inductors in components like transformers, motors, and generators, as well as in RF circuits for measuring the impedance of antennas and resonant circuits.
