Electricity is the flow of electrons. The questions relate to how electricity is quantified.

1. Electrons are charged particles. The amount of charge that passes per unit time is called voltage.

a. potential.
b. current.

2. The driving force for the electrons (i. e., the reason they are flowing in the first place) is measured by:

a. charge
b. current
c. potential

1. (a) Current

2. (b) Potential

Explanation:

1. The correct option is Current.

Electric current is a measure of the amount of charge that passes a particular point per unit time. It is the time rate of flow of electric charge through a point of consideration.

The moving electric charge is made up of electrons moving through an electrical conductor.

Mathematically, current is given as:

Its unit is Amperes (A)

2. The correct option is potential.

Electric potential, V, is the amount of work that is needed to move a charge from one point to another point against an electric field.

It is also known as Electric potential drop or Electrostatic potential.

Its unit is Joules/Coulomb (J/C) or Volts (V).

degree celsius.

a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.

a temperature increase of

5

9

degree fahrenheit is equivalent to a temperature increase of 1 degree celsius.

a) i only

b) ii only

c) iii only
