Answer:

n = 15 x10^19 Electrons

Explanation:

We know that current is defined as the rate of flow of charge or electrons. It can be mathematically written as;

Current = Charge / time

Q = I x t

As per given information

Q = 0.2 x ( 2 x 60 )

Q = 24 columnb

Now we also know that

Q = Ne,

Where n is the number of electrons and E is the charge on one electron

N = Q/ E

n=24 / 1.6*10^(-19)

n=15 x10^19 Electrons

15 × 10¹⁹ electrons pass through a loop in 2 minutes if the current is 200 mA​.

Explanation:

The current flowing through a conductor is given by the formula:

I = q/t

Where,

q = Charges

t = Time

Now, the charge flowing through loop for 120 seconds is:

q = I × t

On substituting the values, we get,

q = 0.2 × 120

∴ q = 24 C

Thus, the number of electrons are given by the formula:

n = q/e

Where,

e = Charge of electrons = 1.6 × 10⁻¹⁹ C

On substituting the values, we get,

n = 24/(1.6 × 10⁻¹⁹)

∴ n = 15 × 10¹⁹
