Exam 17: Inductance in Alternating Current Circuits

When a magnetic field continually changes magnitude and direction, a voltage is continually being induced in the coil. This voltage is called voltage.

Circuits are generally considered to contain when any type of load that contains a coil is used.

Volt-amperes-reactive is used to measure the in a pure inductive circuit.
