Part A
Electric Charge
Two types: positive and negative
Like charges repel; opposite charges attract
Charge is measured in coulombs (C)
Coulomb’s Law
Electric force between charges
Bigger charges → stronger force
Greater distance → weaker force (inverse-square law)
Electric Potential Energy
Energy a charge has because of its position in an electric field
Increases when like charges are pushed together
Decreases when opposite charges come together
Equipotential Surfaces
Surfaces where electric potential is the same everywhere
No work is done when moving along an equipotential
Always perpendicular to electric field lines
Voltage Sources
Devices that maintain a constant potential difference
Examples: batteries, solar cells, generators
Push electric charges through a circuit
Electric Field
Region around a charge where it exerts force
Direction: what a positive test charge would feel
Electric Potential (Voltage)
Potential energy per unit charge
Measured in volts (V)
