CHARGED BODY

Every substance or body is electricity neutral as all the atoms of the body contain equal number of electrons and protons.

(b) Negatively charged body

However, when some electrons are detached from the body, a deficit of electrons occurs. As a result, the body attains positive charge [Fig. 1.2(a)], whereas if the electrons are supplied to a neutral body, then the number of electrons will be more than its normal due share. Hence, the body attains negative charge [Fig. 1.2(b)]. Therefore, a body is said to be charged positive or negative if it has deficit or excess of electrons from its normal due share, respectively.
