Review

This circuit component symbol represents a(n):

70% Answer Correctly

	resistor
	fuse
	diode
	capacitor

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.

Which of the following is not a terminal on a transistor?

59% Answer Correctly

	input
	base
	collector
	emitter

Solution

A transistor works by allowing a small amount of current applied at the base to control general current flow from collector to emitter through the transistor.

3 A circuit with a 120-volt power supply is protected by a 15-amp circuit breaker. What is the largest number of watts loads on this circuit can safely use?

82% Answer Correctly

	1620 W
	1800 W
	900 W
	600 W

Solution

Wattage is current multiplied by voltage: W = IV. So, the maximum amount of power a 120-volt circuit with a 15A circuit breaker would allow is 120V x 15A = 1800 W.

The ohm is a unit of measurement for:

81% Answer Correctly

	resistance
	energy
	power
	capacitance

Solution

Resistance is opposition to the flow of current and is measured in ohms (Ω). One ohm is defined as the amount of resistance that will allow one ampere of current to flow if one volt of voltage is applied. As resistance increases, current decreases as resistance and current are inversely proportional.

A transistor to an electronic circuit is like a _______________ to a house?

68% Answer Correctly

	safe
	driveway
	gate
	no trespassing sign

Solution

A transistor works by allowing a small amount of current applied at the base to control general current flow from collector to emitter through the transistor. A transistor acts as a gate or switch for electronic signals.
