Question

defination of unit charge​

Answer 1

Answer:

units of charge are Coulombs and Ampere–second.

Coulomb is the standard unit of charge. One Coulomb of charge is equal to electrons or protons. One electron is equal to  Coulombs.

The other unit Ampere–second is extracted from current formula as

$i (t) in ampere = \frac{dq (t)}{dt} \frac{columbs}{second}$

Answer 2

An electric charge is the property of matter where it has more or fewer electrons than protons in its atoms. Matter is positively charged if it contains more protons than electrons, and negatively charged if it contains more electrons than protons.
