Electric Potential Review

Flashcards covering key vocabulary and concepts related to electric potential and calculations.

Electric Potential (V)

The amount of electric potential energy per unit charge at a point in space, often calculated with the formula V = kq/r.

Coulomb's Constant (k)

A proportionality factor in the equation for electric potential, equal to approximately 9 x 10^9 N m²/C².

Charge (q)

The property of matter that causes it to experience a force when placed in an electromagnetic field.

Potential at point P

The electric potential at a specific point in an electric field, influenced by surrounding charges.

Zero Potential Point

The point along the line where the total electric potential due to multiple charges is equal to zero.

Negative Charge (-5µC)

A charge with a value of negative five microcoulombs, often used in calculating electric potential.

Formula for Electric Potential due to multiple charges

V = k(q1/r1 + q2/r2 + … + qn/rn), where V is the total potential from multiple point charges.

Relationship between charge and electric potential

The electric potential is directly proportional to the charge and inversely proportional to the distance from that charge.
