A device that is used to provide any one resistance within a wide range of values is a

A graph referred to as the volt-ampere characteristic of R shows how much resistance exists for different currents.

Opposition, that limits the amount of current that can be produced by the applied voltage is called

In electronic equipment, the resistor most commonly used is the

The resistance of a short circuit is approximately

The practical unit of resistance is the mho.

Resistors have a relatively short shelf life and only keep their characteristics for six to eight months.

An element is defined as a substance that cannot be decomposed any further by chemical action.

A popular test instrument used to measure voltage, current, or resistance is a(n)

Opposition that limits the amount of current that can be produced by the applied voltage is called reluctance.
