Review

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

67% Answer Correctly

	integrated circuits
	series-parallel circuits
	parallel 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.

Which of the following statements about electrical resistance is true?

74% Answer Correctly

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

Solution

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

Which of the following is not a common type of battery?

41% Answer Correctly

	power-cycle
	dry cell
	wet cell
	deep-cycle

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. The three most common types of batteries are dry cell (used in small devices like TV remotes), wet cell (used for cars), and deep-cycle (storage batteries used primarily for backup and emergency power).

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

83% Answer Correctly

	battery
	ammeter
	reostat
	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.

Capacitors store:

68% Answer Correctly

	resistance
	current
	electricity
	capacitance

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.
