1

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

52% Answer Correctly

less than

double

more than

triple
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.

2

A capacitor is often used for which of the following purposes?

68% Answer Correctly

to allow a small amount of current to control a large amount of current

to maintain power in a circuit when the primary power source is disconnected

as a primary power source

to convert alternating current into direct current
Solution

Capacitors store electricity and are used in circuits as temporary batteries. Capacitors are charged by DC current (AC current passes through a capacitor) and that stored charge can later be dissipated into the circuit as needed. Capacitors are often used to maintain power within a system when it is disconnected from its primary power source or to smooth out or filter voltage within a circuit.

3

All electricity is the movement of which subatomic particles?

89% Answer Correctly

protons

nuclei

neutrons

electrons
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.

4

The most common circuit configuration is:

59% Answer Correctly

parallel

series-parallel

series

household
Solution

Circuits are not limited to only series or only parallel configurations. Most circuits contain a mix of series and parallel segments. A good example is a household circuit breaker. Electrical outlets in each section of the house are wired in parallel with the circuit breaker for that section wired in series making it easy to cut off electricity to the parallel parts of the circuit when needed.

5

The farad is a unit of measurement for:

63% Answer Correctly

energy

power

capacitance

inductance
Solution

Capacitors store electricity and are used in circuits as temporary batteries. Capacitors are charged by DC current (AC current passes through a capacitor) and that stored charge can later be dissipated into the circuit as needed. Capacitors are often used to maintain power within a system when it is disconnected from its primary power source or to smooth out or filter voltage within a circuit.
