The ampere is a unit of measurement for:

79% Answer Correctly

	inductance
	current
	energy
	power

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.

Longer the electrical wires mean _______________ voltage drop.

73% Answer Correctly

	lesser
	greater
	diminishing
	complete

Solution

Electrical wires have a certain amount of resistance per foot. A longer wire means more resistance and a greater voltage drop.

The ohm is a unit of measurement for:

81% Answer Correctly

	capacitance
	power
	energy
	resistance

Solution

Resistance is opposition to the flow of current and is measured in ohms (Ω). One ohm is defined as the amount of resistance that will allow one ampere of current to flow if one volt of voltage is applied. As resistance increases, current decreases as resistance and current are inversely proportional.

4 A circuit with a 120-volt power supply is protected by a 15-amp circuit breaker. What is the largest number of watts loads on this circuit can safely use?

82% Answer Correctly

	900 W
	1802 W
	1800 W
	1797 W

Solution

Wattage is current multiplied by voltage: W = IV. So, the maximum amount of power a 120-volt circuit with a 15A circuit breaker would allow is 120V x 15A = 1800 W.

The valence shell of n insulator is how full of electrons?

56% Answer Correctly

	half full
	more than half full
	empty
	less than half full

Solution

Insulators have valence shells that are more than half full of electrons and, as such, are tightly bound to the nucleus and difficult to move from one atom to another.
