Question

What Is Meant By Electric Charge?

Answer 1

1. Electric Charge is the property of subatomic particles that causes them to experience a force when placed in an electromagnetic field.
2. The electric charge is a scalar quantity.
3. The SI unit of electric charge is $\mathrm{Coulomb}\left(\mathrm{C}\right)$
4. Faraday and Ampere-Hour are the other units of electric charge.
5. The mathematical expression for electric charge is
   $$\begin{gathered} \mathrm{electric}\mathrm{charge}=\mathrm{current}\times \mathrm{time} \\ \mathrm{Q}=\mathrm{It} \end{gathered}$$
6. There are two types of electric charge:
   6.1 positive charge: When an object has a positive charge it means that it has more protons than electrons.
   6.2 negative charge: When an object has a negative charge it means that it has more electrons than protons.
7. Like charges repel each other.
8. Unlike charges attract each other.
