Study Notes
Electric Field and Electric Charge
- When the distance between two parallel plates is increased, the electric field between them decreases.
- The SI unit of electric charge is the coulomb (C).
Electric Field Intensity
- The formula to calculate the electric field intensity is Electric field intensity = Force per unit positive test charge.
- Electric field intensity is a vector quantity and its unit is newton per coulomb (N/C).
Electric Force
- When the distance between two charges is doubled, the electric force between them is reduced to one-quarter of its original value, due to the inverse square law.
Electric Potential
- The SI unit of electric potential is the volt (V).
Electric Field and Test Charge
- A positive test charge placed in an electric field experiences a force in the direction of the electric field.
