What is the effect of charge separation in a battery?
It creates an electric potential difference.
What happens when equipotential lines are closer together?
The electric field is stronger.
What happens when a positive charge moves from high to low potential?
It loses electric potential energy.
Define electric potential.
Electric potential is the electric potential energy per unit charge at a point in space; measured in volts (V).
What is electric potential difference?
The change in electric potential energy per unit charge when moving a test charge between two points.
Define equipotential lines.
Lines connecting points of equal electric potential; always perpendicular to electric field vectors.
What are electric field vectors?
Vectors that point in the direction of decreasing potential (from high to low), showing the direction a positive test charge would move.
What is voltage?
Electric potential difference; the driving force behind electric current.
What is the difference between electric potential and electric field?
Electric Potential: Scalar, like height. | Electric Field: Vector, like the slope of that height.
