Properties Of Electric Charges
Charges have 3 basic properties
- 1.
Additive
Additive property indicates that charges
can be added or removed.
Eg if a body has chare q1 and anther body of
charge q2 is induced into it, then net charge will be q = q1 + q2.
- 2.
Conservation of charges
Charges are neither created nor destroyed.
Charges are transferred from one body to another.
Eg if we rub 2 bodies together, electrons
will transfer from one body to other , thus making first body as positively
charges and second as negatively charged.
- 3.
Quantisation of charges
Anything that aquires a charge is always in
multiples of “e”, e denotes tha charge of a single electron
Thus total charge on a body is always = ne,
where n is a positive integer and e is charge of an electron.
Experimentally e = 1.062192 X 10^-19 C
