Review

Which of the following statements about electrical resistance is true?

75% Answer Correctly

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

The sum of the voltage drops across each resistor in a __________ circuit will equal the total voltage applied to the circuit.

54% Answer Correctly

	series
	parallel
	closed
	series-parallel

Solution

A series circuit has only one path for current to flow. In a series circuit, current (I) is the same throughout the circuit and is equal to the total voltage (V) applied to the circuit divided by the total resistance (R) of the loads in the circuit. The sum of the voltage drops across each resistor in the circuit will equal the total voltage applied to the circuit.

This circuit component symbol represents a(n):

57% Answer Correctly

	transformer
	DC source
	capacitor
	AC source

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.

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.

Capacitors store:

68% Answer Correctly

	capacitance
	current
	electricity
	resistance

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.
