1 What's the overall power consumption of a piece of equipment that is rated for 6 amps at 20 volts?

85% Answer Correctly

	120 W
	123 W
	126 W
	108 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 6 amps (I) at 20 volts (V) so the equation becomes P = \( 20 \times 6 \) = 120 W

An amplifier is most similar in function to which of the following:

65% Answer Correctly

	transistor
	capacitor
	step-up transformer
	step-down transformer

Solution

An amplifier is a device that takes a small input signal and creates a larger output signal. This makes it most similar to a step-up transformer which takes a smaller input voltage and creates a larger output voltage.

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

52% Answer Correctly

	triple
	double
	more than
	less than

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.

The valence shell of n insulator is how full of electrons?

56% Answer Correctly

	empty
	less than half full
	more than half full
	half full

Solution

Insulators have valence shells that are more than half full of electrons and, as such, are tightly bound to the nucleus and difficult to move from one atom to another.

Which of the following is the preferred method for splicing wires?

57% Answer Correctly

	wire crimps
	soldering
	screw-on connectors
	wrap in small gauge wire

Solution

Splicing is permanently joining two wires together. Splicing can be done with screw-on connectors or wire crimps but the preferred method for splicing is soldering. Soldering takes the most effort but results in a connection that is electrically and mechanically identical to the original wire.
