If the current flowing through the wire is 1 A, then 1 C can be defined as the charge flowing or passing through a wire in 1 second.
There are certain basic properties of electric charge that they follow. The electric charges are considered as point charges if the size of the electrically charged bodies is so small. Apart from the above-mentioned properties of electric charge, there are certain other basic properties they possess. They are:
According to the addition of property of electric charge, the net charge of a system is an algebraic sum of a charge of an individual subatomic particle.
As we know, the charge present on one proton is e and the charge present on one electron is -e, as well as, the charge present on neutron is zero and it does not depend on the number of neutrons present in the system.
