Question

How many electrons will be there in 1.6 C charge.?​

Answer 1

the number of electrons constituting one coulomb of charge. We know that the a electron have charge of 1.6 × 10−19 C. then 1 coulomb of charge contans = 1/(1.6*10^-19)=6.25*10^18 electrons

Answer 2

Given: Charge - Q = 1.6C

To Find: number of electrons in 1.6C charge

Solution:

1 electron has = 1.6 × 10⁻¹⁹ C

Formula used:

Quantization of charge - charge of any object is an integer multiple of a given value ( here Q = 1.6 × 10⁻¹⁹)

Q = n × qe ( n - number of electron, qe = charge  on 1 electron)

∴ n = Q/qe

Applying the above formula:-

n = 1.6/1.6 × 1/10⁻¹⁹

n = 10¹⁹ electrons

Hence, 10¹⁹ electrons are present in 1.6 C charge.
