1

This circuit component symbol represents a(n):

57% Answer Correctly

AC source

transformer

DC source

capacitor
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.

2

The ampere is a unit of measurement for:

79% Answer Correctly

current

energy

inductance

power
Solution

Current is the rate of flow of electrons per unit time and is measured in amperes (A). A coulomb (C) is the quantity of electricity conveyed in one second by a current of one ampere.

3

A transistor works by allowing a small amount of current to control general current flow. Where is the small amount of current applied?

55% Answer Correctly

base

collector

emitter

input
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.

4

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

52% Answer Correctly

double

more than

triple

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.

5

General current flow in a transistor is from __________ to __________.

51% Answer Correctly

base, emitter

collector, base

base, collector

collector, emitter
