Review

A diode to an electronic circuit is like a _______________ to a city?

67% Answer Correctly

	parking lot
	highway
	traffic light
	one-way street

Solution

A diode allows current to pass easily in one direction and blocks current in the other direction.

2 Suppose you have 10 [15V 15A] batteries that you can connect together in series, in parallel, or in series-parallel. Which of the following voltage and ampere combinations cannot be attained using these 10 batteries?

46% Answer Correctly

	15V 150A
	75V 75A
	150V 150A
	150V 15A

Solution

Connecting the 10 batteries in series multiplies their voltage while keeping their current the same yielding a 150V 15A configuration. Connecting the 10 batteries in parallel multiplies their current while keeping their voltage the same yielding a 15V 150A configuration. Using a series-parallel connection, 5 batteries can be connected in series and 5 can be connected in parallel resulting in a 75V 75A configuration.

In electrical wiring, which of the following are proportional?

49% Answer Correctly

	the diameter of the wire and the amount of the current
	the diameter of the wire and the amount of the voltage
	the length of the wire and the amount of the current
	the length of the wire and the amount of the voltage

Solution

Current flow through a wire increases the temperature of the wire. If too small a wire is used, the wire will heat up causing a loss in conductivity and possibly a fire. The thicker in diameter a wire is, the more current it can carry without overheating.

4 How would you connect 4 [9V 20A] batteries to achieve a combined power output of 9V 80A?

51% Answer Correctly

	series
	series-parallel
	parallel
	orthogonal

Solution

Connecting the 4 batteries in series multiplies their voltage while keeping their current the same yielding a 36V 20A configuration. Connecting the 4 batteries in parallel multiplies their current while keeping their voltage the same yieleding a 9V 80A configuration. Using a series-parallel connection, 2 batteries can be connected in series and 2 can be connected in parallel resulting in a 18V 40A configuration.

You would measure the amount of voltage between two points in a circuit with a(n):

83% Answer Correctly

	voltmeter
	battery
	ammeter
	reostat

Solution

Voltage (V) is the electrical potential difference between two points. A voltmeter is used to measure the voltage between two points in a circuit.
