VARs is an abbreviation for ____.

In a pure inductive circuit, ____.

In a pure inductive circuit the current ____.

The amount of induced voltage in an inductor can be computed if the resistance of the wire in the coil and ____ are known.

An induced voltage ____ the applied voltage.

An electrical measurement called ____ is used to measure the reactive power in a pure inductive circuit.

An inductor has an inductance of 0.8 H and is connected to a 120-V, 60-Hz line. How much current will flow in this circuit if the wire resistance of the inductor is negligible?

A great amount of true power is produced in a pure inductive circuit.

The schematic symbol used to represent an inductor depicts a coil of wire.

How much voltage is necessary to push 0.8 A of current through 6 ohms of resistance?

The amount of induced voltage is proportional to the ____.

The greatest rate of current change occurs when the current passes from negative through zero and begins to increase in the positive direction.

Sometimes the current will rise and fall at the same rate as the voltage and will reverse the direction of flow when the voltage reverses polarity. In this condition, the current is said to be ____ with the voltage.
