Key Points
- Electric charge is a fundamental property of matter that causes the matter to experience a force when kept in electric and magnetic fields.
- There are two types of charges possessed by matter - negative charge and positive charge.
- The matter that is neither positive nor negative is said to be neutral.
- The electric charge of the matter comes from the charge carried by electrons and protons at the atomic level.
- The SI unit of electric charge is coulomb (C).
EXPLANATION:
- Electric charge is measured in the SI unit coulomb (C).
- Electric current (I) is defined as the charge flowing per unit time.
Where I is current, q is the charge and t is the time.
So, 1 coulomb is the charge from a current of 1 A flowing in 1 s.
- Charge of an electron = 1.6 × 10-19 C
Number of electrons in 1 C =
So 1C (Approx) = 6 × 1018
