17 Questions
What is the relationship between electric potential and electrical potential energy?
Electric potential is the ratio of electrical potential energy per charge
Can a capacitor store both energy and charge?
Can store energy and charge
What happens to the electric field inside a conducting sphere of a Van de Graaff generator as it charges?
Nothing; the field is always zero
When does an electric field shield inside a conductor?
When the conductor has a non-uniform charge distribution
How does a change in polarity affect the electric potential energy of a system?
No effect on the electric potential energy
What is the SI unit of measurement for electric potential?
Volt
How is potential energy measured?
Joules
What does a potential of 1 volt represent?
1 joule of energy per coulomb of charge
Why is it said that a potential of 1000 V means that 1000 joules of energy per coulomb is needed to bring a small charge from very far away and add it to the charge on the conductor?
To emphasize the relationship between voltage and energy per charge
If there were twice as much charge on an object, what would happen to its electrical potential energy?
It would be twice as great
What would happen to the electric potential if twice as much charge was present on an object?
It would remain the same
What is the term for the energy a charge has due to its location in an electric field?
Electric potential energy
When pushing a positive test charge closer to a positively charged sphere, what type of energy is overcome?
Electrical repulsion
What is the term used to describe the electrical potential energy per charge?
Electric potential
Why is it mentioned that the electric potential of any charge at the same location is the same?
To highlight equipotential surfaces
When rubbing a balloon on hair, what causes the balloon to become negatively charged?
Absorption of electrons by the balloon
What can be said about the electrical potential energy of an object with greater charge compared to an object with less charge within an electric field?
It remains the same as electric potential does not depend on charge amount
