Question

How many electrons will flow through a wire when the charge of 4C flows for 2 sec? Also find the current.

Answer 1

Number of electrons = $\frac{\text{Charge Flow}}{\text{Charge on 1 electron}}=\frac{4}{1.6\times {10}^{-19}}=2.5\times {10}^{19}$

Current in the circuit = $\frac{ChargeFlown\left(inCoulomb\right)}{TimeTaken}=\frac{4}{2}=2Ampere$
