Some particles have an electric charge.Electric charge is a fundamental property of matter and is measured in coulombs(C).Charge is always conserved because it is impossible to create or destroy charge.Charge can be negative or positive.The amount of charge on an electron is -1.6 × 10-19 C.The amount of charge on a proton is +1.6 × 10-19 C.Positive and negative charges attract.A flow of charge is an electric current.
