Question and Answer

Give three properties of electric charge.

Answer

\(Basic\ properties\ of\ electric\ charge:\)

\(Addivity\ of\ charges\)
Charges are additive in nature means they are like scalars and can be added directly. For an example, consider a system which consists of two charges namely \(q_1\) and \(q_2\). Now we wish to find the total charge of the system. The total charge of the system will be the algebraic sum of \(q_1\) and \(q_2\) i.e. \(q_1+ q_2\).
\(Conservation\ of\ Charge\)
The charge is a conserved quantity which means charge can neither be created nor be destroyed but can be transferred from one body to another by certain methods like conduction and induction.
\(Quantization\ of\ charge\)
Quantization of charge means that charge is a quantized quantity and is expressed as integral multiples of the basic unit of charge (e charge on one electron). Suppose charge on a body is q, then it can be written as \(q = ne\),where n is an integer like 1, 2, 3, -5 etc.
