Impedance
A term used with alternating current circuits to describe the "ac resistance" to the flow of current through a circuit when an ac voltage is applied across the terminals of that circuit. Impedance is a complex quantity composed of real (in phase with voltage) and reactive (out of phase by 90°) components. Impedance is calculated as voltage divided by current. Impedance is the sum of alternating current oppositions (capacitive reactance, inductive reactance and resistance).

Inductor
Abbreviated L (as in LCR). An inductor is a coil of wire. It is used to create electromagnetic induction in a circuit.
Inductance
The property of a coil to oppose any change in current through it. If the turns (coils) of the wire are stretched out, the field intensity will be less and the inductance will be less. Unit of measure is the Henry (H).

Inductance Meter
An inductance meter measures inductance or "L" as in LCR. LCR meters are sometimes referred to as inductance meters for their ability to perform inductance testing.

Inductive Reactance
A measure of how much the counter electro-magnetic force (emf) of the coil will oppose current variation through the coil.
Insulation
The protection against flow of current, as between a circuit of a product and the ground reference. Materials that prevent current flow are referred to as insulators or dielectrics.

Insulation Resistance
Characteristic of an insulating material that being subject to voltage, indicates a resistance such that the value of leakage current which flows through it stays within acceptable limits.
Insulation Resistance Tester
An insulation resistance tester measures a component’s insulation and gives a whole, quantifiable value. An insulation resistance tester uses direct current or DC.

- J -
Joule
A joule (J) is a unit of electrical energy and is equal to the work done when one ampere is passed through a resistor of 1 Ohm for the duration of one second.
- K -
Kelvin Connection
A circuit configuration that automatically compensates for measurement errors caused by resistance of leads between a tester and the point of measurement on a DUT.
