Study Notes

Electric Charge and Electric Field

The fundamental property of matter that gives rise to electric force is electric charge.
The SI unit of electric charge is the coulomb (C).

Electric Field Due to a Positive Charge

The direction of the electric field at a point due to a positive charge is radially outward from the charge.
The electric field due to a positive charge is radial and outward, and its magnitude decreases with distance from the charge.

Electric Potential Energy

When two like charges are brought closer, their electric potential energy increases.

Electric Field and Electric Potential

Electric field and electric potential are related, with the electric field being the negative gradient of the electric potential.
