1 What's the overall power consumption of a piece of equipment that is rated for 9 amps at 30 volts?

85% Answer Correctly

	270 W
	261 W
	272 W
	297 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 9 amps (I) at 30 volts (V) so the equation becomes P = \( 30 \times 9 \) = 270 W

2 How would you connect 8 [6V 10A] batteries to achieve a combined power output of 24V 40A?

67% Answer Correctly

	orthogonal
	series
	parallel
	series-parallel

Solution

Connecting the 8 batteries in series multiplies their voltage while keeping their current the same yielding a 48V 10A configuration. Connecting the 8 batteries in parallel multiplies their current while keeping their voltage the same yieleding a 6V 80A configuration. Using a series-parallel connection, 4 batteries can be connected in series and 4 can be connected in parallel resulting in a 24V 40A configuration.

Longer the electrical wires mean _______________ voltage drop.

73% Answer Correctly

	diminishing
	complete
	lesser
	greater

Solution

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

This circuit component symbol represents a(n):

57% Answer Correctly

	DC source
	capacitor
	transformer
	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.

Which of the following is the preferred method for splicing wires?

57% Answer Correctly

	wire crimps
	screw-on connectors
	wrap in small gauge wire
	soldering

Solution

Splicing is permanently joining two wires together. Splicing can be done with screw-on connectors or wire crimps but the preferred method for splicing is soldering. Soldering takes the most effort but results in a connection that is electrically and mechanically identical to the original wire.
