The watt is a unit of measurement for:

78% Answer Correctly

	power
	resistance
	energy
	frequency

Solution

Electrical power is measured in watts (W) and is calculated by multiplying the voltage (V) applied to a circuit by the resulting current (I) that flows in the circuit: P = IV. In addition to measuring production capacity, power also measures the rate of energy consumption and many loads are rated for their consumption capacity. For example, a 60W lightbulb utilizes 60W of energy to produce the equivalent of 60W of heat and light energy.

Direct current flows from the __________ terminal of the voltage source to the __________ terminal.

62% Answer Correctly

	positive, negative
	negative, negative
	negative, positive
	positive, positive

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.

Which of the following statements about electrical resistance is true?

74% Answer Correctly

	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
	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.

Electrons will flow as current from areas of __________ potential (concentration of electrons) to areas of __________ potential.

74% Answer Correctly

	low, high
	high, low
	low, low
	high, high

Solution

Voltage (V) is the electrical potential difference between two points. Electrons will flow as current from areas of high potential (concentration of electrons) to areas of low potential. Voltage and current are directly proportional in that the higher the voltage applied to a conductor the higher the current that will result.

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.
