GENERAL PHYSICS 2 SUMMATIVE TEST Electric Potential Quiz

What is the SI unit of electric potential?

• Newton

Electric potential is defined as:

• The work done per unit charge to move a charge from one point to another

• The force per unit charge at a point in an electric field

• The total energy stored in an electric field

• The amount of charge stored in a conductor

The potential difference between two points is also known as:

• Resistance

• Current

• Voltage

• Capacitance

What is the formula for the electric potential (V) due to a point charge (q)?

• V = k × q / r

• V = (1/2) m v²

• V = IR

• V = qE

The electron volt (eV) is a unit of:

• Electric charge

• Electric field

• Energy

• Voltage

Which constant is used in Coulomb’s law and electric potential equations?

• Planck’s constant

• Gravitational constant

• Coulomb’s constant

• Boltzmann’s constant

The total electric potential due to multiple charges is obtained by:

• Halves

What happens to the electric potential when the distance from a point charge increases?

• It increases

• It remains the same

• It decreases

• It becomes zero

If a test charge moves along an equipotential surface, the work done by the electric field is:
