Explain the basic fundamentals of electricity

Front

Volts, ohms, and amps are units used to measure which of the following electrical properties?

Back

Voltage, resistance, and current

Front

“Continuity,” “open,” and “short” refer to which of the following?

Back

Electrical circuit conditions: continuity means a complete path, open means a broken path, and short means a direct connection with little or no resistance.

Front

Electrons travel in different rings, or shells, around the nucleus of an atom.

Back

True

Front

What is a negative ion?

Back

An atom with more electrons than protons.

Front

Fill in the blank: The flow of electrons from atom to atom is called ______ and is the basic concept of electricity.

Back

current flow

Front

Refer to FIGURE 6. Which of the following is an insulator? Cu, Ar, Si

Back

Ar

Front

Refer to FIGURE 6. Which of the following is a semiconductor? Cu, Ar, Si

Back

Si

Front

What is an insulator?

Back

An insulator is a material that does not conduct electrons easily. It does not allow current flow because it has no or very few free electrons, and the electrons it does have cannot move freely.

Front

What is a semiconductor?

Back

A semiconductor is a material that conducts electricity more easily than insulators, but not as well as conductors. Semiconductors such as silicon are crucial in electronics and can switch between being a conductor and an insulator.

Front

What effect does increasing the diameter of a conductor have on the amount of current it can carry?

Back

The larger the conductor, the greater the amount of current it can carry.
