Answer :
The number of electrons that constitute 1A of current is 6.25 x 10^(18). The correct option is (c).
The number of electrons that constitute 1A of current can be determined using Faraday's constant, which represents the charge carried by one mole of electrons. Faraday's constant is approximately 96,485 Coulombs per mole of electrons.
To calculate the number of electrons constituting 1A of current, we need to divide the current (in Amperes) by the charge carried by one electron (in Coulombs). The charge carried by one electron is the elementary charge, denoted as e, which is approximately 1.6 x 10^(-19) Coulombs.
Therefore, the number of electrons (N) can be calculated as:
N = (1A) / (1.6 x 10^(-19) C)
N ≈ 6.25 x 10^(18)
Hence, the correct option is (c) 6.25 x 10^(18).
