Electric Charge and Electric Fields

Front

is either a positive or negative type that is the basic property of matter carried by some elementary particles that govern how the particles are affected by an electric or magnetic field and is neither created nor destroyed.

Back

is a physical quantity that has both magnitude and direction.

Back

vector quantity

Front

The charge that is used to measure the electric field strength is referred to as a test charge.

Back

test charge

Front

is the energy needed to move an electric charge in an electric field.

Back

electric potential energy

Front

is the amount of work to move an electric charge from a reference point to a specific point on an electric field.

Back

electric potential

Front

is the change in potential energy of charge q moved from point A to B divided by the charge.

Back

potential difference
