1

What is the voltage of most household electrical systems in the United States?

59% Answer Correctly

110V

60Hz

220V

60V
Solution

Most households use electricity with a voltage of 110V.

2

You would measure the amount of resistance at a certain point in a circuit with a(n):

78% Answer Correctly

voltmeter

ammeter

ohmmeter

potentiometer
Solution

Resistance is opposition to the flow of current and is measured in ohms (Ω). An ohmmeter is used to measure the amount of resistance at a certain point in a circuit.

3

In an electronic circuit, a thermocouple can be used to:

42% Answer Correctly

keep the circuit at a designated safe temperature

increase or decrease the temperature of a component in the circuit

open or close a circuit at a designated temperature

link the temperature of one component in the circuit to that of another component in the circuit
Solution

A thermocouple is a temperature sensor that consists of two wires made from different conductors. The junction of these two wires produces a voltage based on the temperature difference between them and can be used like a switch to open or close the circuit at a designated temperature.

4

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

68% Answer Correctly

driveway

safe

gate

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.

5

This circuit component symbol represents a(n):

67% Answer Correctly

transformer

transistor

diode

inductor
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.
