Which of the following will help to prevent a short circuit?

74% Answer Correctly

	fuse
	resistor
	diode
	transistor

Solution

Fuses are thin wires that melt when the current in a circuit exceeds a preset amount. They help prevent short circuits from damaging circuit components when an unusually large current is applied to the circuit, either through component failure or spikes in applied voltage.

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

52% Answer Correctly

	double
	triple
	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.

Using a fuse with a current rating higher than that required by a circuit:

70% Answer Correctly

	is recommended
	makes no difference
	is required
	makes the circuit less safe

Solution

A fuse is a type of low resistance resistor that stops current flow in a circuit in response to a larger than intended electric current flow. Using a fuse with a higher current rating than required by a circuit is less safe as it could potentially allow overcurrent and risk a fire or heat-related equipment damage.

This circuit component symbol represents a(n):

57% Answer Correctly

	AC source
	capacitor
	transformer
	DC source

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.

An engineer who wants to document an electric circuit would create which of the following?

67% Answer Correctly

	a blueprint
	a matrix
	a schematic
	a layout

Solution

A schematic is the proper name for a drawing of an electric or electronic circuit.
