1

This circuit component symbol represents a(n):

57% Answer Correctly

capacitor

DC source

transformer

AC source


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 rate of flow of electrons per unit time is which of the following?

74% Answer Correctly

resistance

voltage

current

conductance


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

68% Answer Correctly

driveway

no trespassing sign

gate

safe


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.


4

This circuit component symbol represents a(n):

66% Answer Correctly

transistor

AC source

transformer

DC source


Solution

In contrast to the constant one-way flow of direct current, alternating current changes direction many times each second. Electricity is delivered from power stations to customers as AC because it provides a more efficient way to transport electricity over long distances.


5

The joule is a unit of measurement for:

67% Answer Correctly

capacitance

resistance

energy

power


Solution

The joule is a unit of measurement for energy.
