Question

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

Answer 1

Answer:

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:

$Current = \frac{charge}{time} = \frac{Q}{t}$

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).

Answer 2

By definition:

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

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

1.

Electric current is the net flow of electric charge that circulates in an orderly manner through a conductive material medium. Said material medium can be solid, liquid or gaseous and the charges are transported by the movement of electrons or ions.

That is, electric current is defined as a displacement of electrons carrying electric charge along a conductor between whose ends a potential difference is applied.

In other words, an electric current is the flow of electric charge that passes through a conductive material during a certain period of time and is measured in Ampere (A).

Finally, electrons are charged particles. The amount of charge that passes per unit time is called current.

2.

The electric potential, or electrostatic potential at a point, is the work that an electrostatic field must do to move a positive charge from that point to the reference point.

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

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