Question 1

What are the two types of ammeters?

Accepted Answer

The two ammeter types are the in-line and clamp-on ammeter.

Question 2

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

Accepted Answer

direct

Question 3

_____________________ are much more accurate than voltage testers.

Accepted Answer

Voltmeters

Question 4

Amperage is the rate of flow of the electrons.

Accepted Answer

This is correct. Ampere (A) is the unit of measurement for amperage, which is the rate of flow of electrons in a circuit.

Question 5

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

Accepted Answer

The answer of ____________________ is the speed at which the...

Question 6

Electricity is the flow of ____________________ through a circuit.

Accepted Answer

The answer of Electricity is the flow of ____________________ through...

Question 7

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

Accepted Answer

The answer of The rate at which an electrical load...

Question 8

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

Accepted Answer

Nonlinear loads can include devices such as computers, fluorescent lights, and electronic ballasts. These loads exhibit varying impedance depending on the level of voltage and current applied to them, making them nonlinear in nature.

Question 9

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

Accepted Answer

Voltmeters are used to measure electrical potential difference, not resistance to the earth. To determine the resistance to earth through a grounding electrode, an earth resistance tester or ground tester is needed.
