Amperage is the rate of flow of the electrons.

• True

• False

An ammeter is an instrument that measures a precise amount of voltage.

• True

• False

Opposition to electron flow is called resistance.

• True

• False

Voltmeters are used to determine the amount of resistance to the earth when the resistance to earth through a grounding electrode is unknown.

• True

• False

Nonlinear loads are load types where the load impedance is not constant.
