PHY113-2 (Electric Potential)

The potential energy per unit charge is called the

• electric potential

• electric capacity

• electric charge

• electric change

Work done by the gravitational force

Work done by the gravitational force from a height of A to B

Electric potential formula

Potential different between points formula

This is often used to express the difference (final value minus initial value) in potentials and in potential energies

Which is true about the acceleration of charge from regions of electric potential

• A positive charge accelerates from a region of higher electric potential toward a region of lower electric potential.

• A negative charge accelerates from a region of lower potential toward

  a region of higher potential.

• A negative charge accelerates from a region of lower electric potential toward a region of lower electric potential.

• A positive charge accelerates from a region of higher potential toward

  a region of higher potential.

It is the magnitude of the amount by which the potential energy of an electron changes when the electron moves through a potential

difference of one volt.
