Question

calculate the number of electrons That Flow per second to constitutes a current of 1 ampere. charge on an electron is 1.6 ×10^-19 C.​

Answer 1

Answer:

6.25×10^18

Explanation:

According to the given question,

I = Current = 1 Amp

t = time = 1 sec

e = charge of electron = 1.6×10^-19

n = no of electrons

Q = total charge

And we are asked to find the total numbers of electrons.

We know,

• I = Q/t

Putting the values we get

• 1 = Q/1

• Q = 1 C

We also know,

• Q = ne

putting the given values we get

• 1 = n× 1.6×10^-19

• n = 1/1.6×10^-19

• n = 10^19/1.6

• n = 0.625 × 10^19

• n = 6.25×10^18

Therefore, Total number of electrons is 6.25×10^18 when 1 Amp of current flows for 1 sec.
