Electric Current(I)

If the charge...

Question

If the charge on an electron be $1.6 \times 10^{- 19}$ C, __ electrons should pass through a conductor in 1 second to constitute 1 ampere current.

Open in App

Solution

We know that, n = $\frac{q}{e}$ = $\frac{I t}{e}$ = $\frac{1 \times 1}{1.6 \times 10^{- 19}}$ = $6.25 \times 10^{18}$
