Review

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

67% Answer Correctly

	highway
	traffic light
	one-way street
	parking lot

Solution

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

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

75% Answer Correctly

	high, high
	low, low
	high, low
	low, 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.

Which of the following is not a common type of battery?

41% Answer Correctly

	dry cell
	deep-cycle
	wet cell
	power-cycle

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. The three most common types of batteries are dry cell (used in small devices like TV remotes), wet cell (used for cars), and deep-cycle (storage batteries used primarily for backup and emergency power).

What type of current flows in only one direction in a circuit?

82% Answer Correctly

	alternating
	series
	direct
	parallel

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.

In electrical wiring, which of the following are proportional?

50% Answer Correctly

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