Electric Charge:
A property of microscopic particles, which may be either positive (e.g. protons) or negative (e.g.electrons). Particles with the same charge repel each other, and particles with opposite charges attract each other. The field of force that surrounds an electric charge is called an electric field, and a river of charged particles flowing through a conductor is called an electric current.

Electric Field:
The field of force that surrounds an electric charge (in the same way as a magnetic field is the field of force that surrounds a magnet). Together, the electric and magnetic fields make up the electromagnetic field which underlies light and other electromagnetic waves, and changes in either field will induce changes in the other, as shown in the equations of James Clerk Maxwell.
