Study Notes
Electric Field and Charge
- Electric field lines are a way to visualize the electric field around a charge or a distribution of charges.
Units of Electric Charge
- The SI unit of electric charge is the Coulomb (C).
Electric Field Between Parallel Plates
- When the distance between two parallel plates is increased, the electric field between them decreases.
Electric Field Inside a Conductor
- In electrostatic equilibrium, the electric field inside a conductor is zero.
Electric Field Intensity and Distance
- The electric field intensity (E) is inversely proportional to the square of the distance (r) from a point charge, i.e., E ∝ 1/r².
Gauss's Law
- Gauss's law states that the net electric flux (Φ) through any closed surface is proportional to the total charge (Q) enclosed within the surface, i.e., Φ ∝ Q.
