Review

The ampere is a unit of measurement for:

79% Answer Correctly

	energy
	inductance
	power
	current

Solution

Current is the rate of flow of electrons per unit time and is measured in amperes (A). A coulomb (C) is the quantity of electricity conveyed in one second by a current of one ampere.

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
	electrically conductive materials have no resistive properties
	the more resistive the conductor is the slower 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.

This circuit component symbol represents a(n):

72% Answer Correctly

	capacitor
	inductor
	resistor
	potentiometer

Solution

Resistors are used to limit voltage and/or current in a circuit and can have a fixed or variable resistance. Variable resistors (often called potentiometers or rheostats) are used when dynamic control over the voltage/current in a circuit is needed, for example, in a light dimmer or volume control.

Current is the rate of flow of electrons per unit time and is measured in:

69% Answer Correctly

	volts
	amperes
	coulombs
	ohms

Solution

Current is the rate of flow of electrons per unit time and is measured in amperes (A). A coulomb (C) is the quantity of electricity conveyed in one second by a current of one ampere.

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.
