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.
