$\huge\fcolorbox{red}{aqu}{Answer:}$

Electric charges are of two general types: positive and negative. Two objects that have an excess of one type of charge exert a force of repulsion on each other when relatively close together. Charge thus exists in natural units equal to the charge of an electron or a proton, a fundamental physical constant.
