1 What's the overall power consumption of a piece of equipment that is rated for 6 amps at 30 volts?

80% Answer Correctly

	180 W
	162 W
	181.5 W
	540 W

Solution

Power is measured in watts (W) and 1 watt equals 1 ampere multiplied by 1 volt: P = \( V \times I \). For this problem, the equipment is rated for 6 amps (I) at 30 volts (V) so the equation becomes P = \( 30 \times 6 \) = 180 W

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

56% Answer Correctly

	more than half full
	half full
	less than half full
	empty

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.

Why does current in an electric circuit create heat?

77% Answer Correctly

	heat is created when the current overcomes resistance in the wire
	voltage is naturally hot
	current is naturally hot
	the wire in the circuit burns when current passes through

Solution

Current in an electric circuit creates heat when the current overcomes resistance in the wire.

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

62% Answer Correctly

	negative, negative
	positive, positive
	positive, negative
	negative, 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.

Longer the electrical wires mean _______________ voltage drop.

73% Answer Correctly

	complete
	diminishing
	greater
	lesser

Solution

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