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

Opposition to electron flow is called resistance.

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

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

____________________ is the speed at which the current reverses direction in an alternating current circuit.

____________________ cause distortion of the voltage and current AC waveforms.

Electricity is the flow of ____________________ through a circuit.

The rate at which an electrical load uses electrical energy or the rate at which electrical energy is produced is called _____________________.

In ____________________ current systems the current flows in one direction only.

____________________ are much more accurate than voltage testers.

____________________ are designed to measure more than one electrical value.

Name the unit of measure for current.

What is the equation that represents Ohm’s Law?

What are the three ways that PV modules or batteries can be wired together to get a desired system voltage and current?

What is the procedure for testing a circuit with a voltmeter if the polarity is unknown?

The two types of ammeters are:

Alternating current (AC) is transmitted at high voltages because:

What voltage and phase are residential applications?
