Electric Potential Difference Quiz

What is the primary focus of electric potential difference in this video?

• Gravitational fields

• Magnetic fields

• Parallel plates

• Point charges

Which of the following is measured in joules?

• Potential difference

• Electric field strength

• Electric potential

• Electric potential energy

How is electric potential difference defined?

• Change in charge per unit potential energy

• Change in kinetic energy per unit charge

• Change in potential energy per unit charge

• Change in electric field per unit distance

What is the unit of potential difference?

• Newton

• Joule

• Volt

• Coulomb

What happens to potential energy when a charge moves back to its original position?

• It is converted to thermal energy

• It remains constant

• It is converted to kinetic energy

• It is lost

What is the relationship between work done and potential energy change?

• Work done is double the potential energy change

• Work done is unrelated to potential energy change

• Work done is equal to potential energy change

• Work done is half of potential energy change

Which equation is used to calculate potential difference between parallel plates?

• Potential difference = electric field strength / charge

• Potential difference = charge / electric field strength

• Potential difference = electric field strength × distance

• Potential difference = charge × distance

Why can the formula for potential difference only be used for parallel plates?

• Because they have a varying electric field

• Because they have a uniform electric field

• Because they have a non-uniform electric field

• Because they have no electric field

What is the unit of electric field strength in terms of potential difference?

• Coulombs per meter

• Joules per meter

• Volts per meter

• Newtons per meter

How are volts per meter and newtons per coulomb related?

• They are unrelated

• Volts per meter is twice newtons per coulomb

• Volts per meter is equal to newtons per coulomb

• Volts per meter is half newtons per coulomb
