Review

Which of the following is not a purpose of a resistor in an electrical circuit?

70% Answer Correctly

	limit the current in the circuit
	moderate the heat in the circuit
	control the voltage in the circuit
	multiply the current in the circuit

Solution

Resistors can be chosen in a wide variety of values to control the voltage in a circuit, limit the current, or moderate the heat produced by the components in the circuit.

General current flow in a transistor is from __________ to __________.

50% Answer Correctly

	collector, emitter
	base, emitter
	base, collector
	collector, base

Solution

The transistor is the foundation of modern electronic devices. It is made entirely from semiconductor material (making it a solid state device) and can serve many different functions in a circuit including acting as a switch, amplifier, or current regulator. 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 What's the overall power consumption of a piece of equipment that is rated for 3 amps at 50 volts?

85% Answer Correctly

	135 W
	300 W
	150 W
	151 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 3 amps (I) at 50 volts (V) so the equation becomes P = \( 50 \times 3 \) = 150 W

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

52% Answer Correctly

	less than
	more than
	double
	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.

Longer the electrical wires mean _______________ voltage drop.

73% Answer Correctly

	lesser
	diminishing
	complete
	greater

Solution

Electrical wires have a certain amount of resistance per foot. A longer wire means more resistance and a greater voltage drop.
