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.
What is voltage?
Electric potential difference; the driving force behind electric current.
Define equipotential lines.
Lines that connect points of equal electric potential. No work is done moving a charge along these lines.
What do electric field vectors indicate?
The direction a positive test charge would move; they point in the direction of decreasing potential (from high to low).
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.
