Review

A transistor to an electronic circuit is like a _______________ to a house?

68% Answer Correctly

	driveway
	gate
	safe
	no trespassing sign

Solution

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. A transistor acts as a gate or switch for electronic signals.

2 Use Ohm's Law to calculate the value of voltage in this circuit if resistance is 40 Ω and current is 5 amps.

85% Answer Correctly

	300 V
	200 V
	194 V
	180 V

Solution

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

V = \( I \times R \) = \( 5 \times 40 \) = 200 V

The joule is a unit of measurement for:

67% Answer Correctly

	power
	energy
	capacitance
	resistance

Solution

The joule is a unit of measurement for energy.

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

77% Answer Correctly

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

Solution

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

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

83% Answer Correctly

	voltmeter
	reostat
	battery
	ammeter

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.
