Study Notes
Electric Field and Charge
- The direction of the electric field due to a positive charge is radially outward from the charge.
- The SI unit of electric charge is the coulomb (C).
Conductors
- A conductor is a material that allows electric charges to move freely.
Electric Field Strength
- The electric field strength decreases with an increase in distance from a point charge, following the inverse square law.
Electron Movement
- An electron moves in the opposite direction of the electric field, i.e., it moves from a region of higher potential to a region of lower potential.
Electric Potential Energy
- When two like charges are brought closer together, their electric potential energy increases.
