1

Which of the following converts electrical energy into another form of energy in an electrical circuit?

61% Answer Correctly

wiring

AC source

load

DC source
Solution

A load is a source of resistance that converts electrical energy into another form of energy. The components of a microwave, for example, are loads that work together to convert household electricity into radation that can be used to quickly cook food.

2 Use Ohm's Law to calculate the value of voltage in this circuit if resistance is 60 Ω and current is 3 amps.
85% Answer Correctly
360 V
172 V
270 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 = \( I \times R \) = \( 3 \times 60 \) = 180 V

3

Current is the rate of flow of electrons per unit time and is measured in:

69% Answer Correctly

coulombs

volts

ohms

amperes
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.

4

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

52% Answer Correctly

less than

double

more than

triple
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

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

74% Answer Correctly

current

resistance

conductance

voltage
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.
