Review

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

65% Answer Correctly

	step-down transformer
	step-up transformer
	capacitor
	transistor

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.

What type of current flows in only one direction in a circuit?

82% Answer Correctly

	alternating
	series
	parallel
	direct

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.

A diode to an electronic circuit is like a _______________ to a city?

67% Answer Correctly

	parking lot
	one-way street
	traffic light
	highway

Solution

A diode allows current to pass easily in one direction and blocks current in the other direction.

Which of the following statements about electrical resistance is true?

75% Answer Correctly

	the more resistive the conductor is the faster electron flow will be
	the less resistive the conductor is the slower electron flow will be
	the more resistive the conductor is the slower electron flow will be
	electrically conductive materials have no resistive properties

Solution

Resistance is opposition to the flow of current. As resistance increases, current decreases as resistance and current are inversely proportional.

Alternating current changes __________ many times each second.

72% Answer Correctly

	frequency
	resistance
	period
	direction

Solution

In contrast to the constant one-way flow of direct current, alternating current changes direction many times each second. Electricity is delivered from power stations to customers as AC because it provides a more efficient way to transport electricity over long distances.
