Electric Potential (V)

This is the electric potential energy per unit charge.

conservation of energy

For conservative forces, such as the electrostatic force,_______ states that mechanical energy is a constant.

Mechanical energy

is the sum of the kinetic energy and potential energy of a system; that is, KE + PE = constant

equipotential lines

is a line along which the electric potential is constant.

equipotential surface

is a 3D version of equipotential lines

Equipotential lines

are perpendicular to electric field lines

grounding

process by which conductor can be fixed at zero volts connecting it to the earth with a good conductor is called ____.

capacitor

is a device used to store electric charge.

voltage applied and the capacitor’s physical characteristics

The amount of charge Q a capacitor can store depends on two major factors—the ________, such as its size.

Dielectric

 Is an insulating material of a capacitor
