Question

Write the formula for the current in terms of number of electrons

Answer 1

Answer:

I = Q/t. The S.I unit of current is called ampere (A) (coulomb/second). In metallic conductors the current is due to the motion electrons whereas in electrolytes and ionized gases, both electrons and positive ions move in opposite direction.

Answer 2

Explanation:

we know that

I = q/t

I = current

q = electric charge

t = time

so

q = it ----------(1)

we know that

q = ne -------(2)

n = number of electrons

e = the value of charge on electron

from equation (1) and (2)

we get

it = ne

I = ne/t
