Review

Which of the following allows encapsulating complex circuit designs for easier integration into electronic devices and machines?

67% Answer Correctly

	series-parallel circuits
	parallel circuits
	integrated circuits
	series circuits

Solution

Circuits containing transistors are packaged into integrated circuit chips that allow encapsulating complex circuit designs (CPU, memory, I/O) for easier integration into electronic devices and machines.

This circuit component symbol represents a(n):

66% Answer Correctly

	fuse
	diode
	capacitor
	potentiometer

Solution

Capacitors store electricity and are used in circuits as temporary batteries. Capacitors are charged by DC current (AC current passes through a capacitor) and that stored charge can later be dissipated into the circuit as needed. Capacitors are often used to maintain power within a system when it is disconnected from its primary power source or to smooth out or filter voltage within a circuit.

A capacitor is often used for which of the following purposes?

68% Answer Correctly

	to allow a small amount of current to control a large amount of current
	to maintain power in a circuit when the primary power source is disconnected
	to convert alternating current into direct current
	as a primary power source

Solution

You would measure the amount of voltage between two points in a circuit with a(n):

83% Answer Correctly

	reostat
	battery
	ammeter
	voltmeter

Solution

Voltage (V) is the electrical potential difference between two points. A voltmeter is used to measure the voltage between two points in a circuit.

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

67% Answer Correctly

	highway
	traffic light
	one-way street
	parking lot

Solution

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