Magnitude of charge on one electron, e = 1.6 × 10–19 Coulomb. According to the quantization of charge, charges of the particle (q) are integral multiple of charge of an electron/proton (e). i.e., q = ne. Therefore, number of charges in a coulomb,
= 0.625 x1019
Clearly shows that one coulomb of charge is bigger than the charge on electron and quantization of charge is the correct reason for it. So, both assertion and reason are true.

Assertion (A): A coulomb of charge is bigger than the charge on electron.
Reason (R): Electric charge is always quantized.
Explanation:
To understand this assertion and reason, we need to have a clear understanding of the basic units of electric charge.
1. Electric Charge:
- Electric charge is a fundamental property of matter, and it can be positive or negative.
- The electron is a subatomic particle that carries a negative charge, denoted as "e".
- The proton, another subatomic particle, carries a positive charge equal in magnitude to the electron's charge.
- The Coulomb (C) is the SI unit of electric charge.
2. Assertion (A): A coulomb of charge is bigger than the charge on an electron.
- This assertion is true.
- The charge on an electron is -1.6 x 10^-19 Coulombs (C). It is the basic unit of electric charge for negative charges.
- A coulomb is defined as the charge transported by a constant current of one ampere (A) in one second.
- Therefore, one coulomb (1 C) is equivalent to the charge of approximately 6.25 x 10^18 electrons.
3. Reason (R): Electric charge is always quantized.
- This reason is also true.
- Electric charge is quantized, meaning it exists in discrete amounts or multiples of a fundamental unit.
- The fundamental unit of charge is the charge on an electron, which is -1.6 x 10^-19 C.
- All electric charges in nature are integral multiples of this fundamental unit.
Explanation of Correct Answer:
The correct answer is option 'A': Both Assertion (A) and Reason (R) are true, and Reason (R) is the correct explanation of Assertion (A).
- The assertion states that a coulomb of charge is bigger than the charge on an electron, which is true as explained above.
- The reason for this is that electric charge is always quantized, and the fundamental unit of charge is the charge on an electron.
- As a result, one coulomb is equivalent to a large number of electrons, making it bigger in magnitude than the charge on a single electron.
- Therefore, the reason correctly explains why a coulomb of charge is bigger than the charge on an electron.
Summary:
- The charge on an electron is -1.6 x 10^-19 C, which is the basic unit of electric charge for negative charges.
- A coulomb of charge is bigger than the charge on an electron because electric charge is quantized, and one coulomb is equivalent to a large number of electrons.
- Both the assertion and reason are true, with the reason correctly explaining the assertion.
