Review

The valence shell of a semiconductor is how full of electrons?

67% Answer Correctly

	less than half full
	empty
	more than half full
	half full

Solution

Semiconductors have valence shells that are exacly half full and can conduct electricity under some conditions but not others. This property makes them useful for the control of electrical current.

You would measure the amount of resistance at a certain point in a circuit with a(n):

78% Answer Correctly

	potentiometer
	ohmmeter
	voltmeter
	ammeter

Solution

Resistance is opposition to the flow of current and is measured in ohms (Ω). An ohmmeter is used to measure the amount of resistance at a certain point in a circuit.

The diameter of a number 12 wire is __________ the diameter of a number 6 wire?

52% Answer Correctly

	triple
	more than
	less than
	double

Solution

The larger the number the smaller the diameter of the wire. So, the diameter of a number 12 wire is less than the diameter of a number 6 wire.

This circuit component symbol represents a(n):

57% Answer Correctly

	transformer
	DC source
	AC source
	capacitor

Solution

Direct current flows in only one direction in a circuit, from the negative terminal of the voltage source to the positive. A common source of direct current (DC) is a battery.

The conductivity of an element depends on how many electrons occupy which electron shell?

78% Answer Correctly

	inner
	first
	outer
	middle

Solution

All electricity is the movement of electrons which are subatomic particles that orbit the nucleus of an atom. Electrons occupy various energy levels called shells and how well an element enables the flow of electrons depends on how many electrons occupy its outer (valence) electron shell.
