1 What's the overall power consumption of a piece of equipment that is rated for 2 amps at 80 volts?

80% Answer Correctly

	240 W
	160 W
	80 W
	153 W

Solution

Power is measured in watts (W) and 1 watt equals 1 ampere multiplied by 1 volt: P = \( V \times I \). For this problem, the equipment is rated for 2 amps (I) at 80 volts (V) so the equation becomes P = \( 80 \times 2 \) = 160 W

All electricity is the movement of which subatomic particles?

89% Answer Correctly

	protons
	electrons
	nuclei
	neutrons

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.

Which of these materials is not a good conductor of electricity?

79% Answer Correctly

	tin
	air
	gold
	copper

Solution

All conductors have resistance and the amount of resistance varies with the element. In general, metals make the best conductors of electricity and non-metals make the worst conductors of electricity.

The hertz is a unit of measurement for:

81% Answer Correctly

	energy
	frequency
	inductance
	power

Solution

The hertz is a unit of measurement for frequency.

Electrons will flow as current from areas of __________ potential (concentration of electrons) to areas of __________ potential.

74% Answer Correctly

	high, high
	low, low
	high, low
	low, high

Solution

Voltage (V) is the electrical potential difference between two points. Electrons will flow as current from areas of high potential (concentration of electrons) to areas of low potential. Voltage and current are directly proportional in that the higher the voltage applied to a conductor the higher the current that will result.
