The hertz is a unit of measurement for:

81% Answer Correctly

	frequency
	power
	energy
	inductance

Solution

The hertz is a unit of measurement for frequency.

This circuit component symbol represents a(n):

67% Answer Correctly

	transistor
	inductor
	diode
	transformer

Solution

The transistor is the foundation of modern electronic devices. It is made entirely from semiconductor material (making it a solid state device) and can serve many different functions in a circuit including acting as a switch, amplifier, or current regulator. A transistor works by allowing a small amount of current applied at the base to control general current flow from collector to emitter through the transistor.

The formula specifying Ohm's law is which of the following?

76% Answer Correctly

	V = IR
	\(V = {R \over I}\)
	\(V = {I \over R}\)
	V = I²R

Solution

Ohm's law specifies the relationship between voltage (V), current (I), and resistance (R) in an electrical circuit: V = IR.

4 Use Ohm's Law to calculate the value of resistance in this circuit if voltage is 765 volts and current is 8.5 amps.

80% Answer Correctly

	270 Ω
	180 Ω
	90 Ω
	81 Ω

Solution

Ohm's law specifies the relationship between voltage (V), current (I), and resistance (R) in an electrical circuit: V = IR.

Solved for resistance, R = \( \frac{V}{I} \) = \( \frac{765}{8.5} \) = 90 Ω

The diameter of a number 12 wire is __________ the diameter of a number 6 wire?

52% Answer Correctly

	triple
	more than
	double
	less than

Solution

The larger the number the smaller the diameter of the wire. So, the diameter of a number 12 wire is less than the diameter of a number 6 wire.
