A conductor carries a current of 0.2A. Find the amount of charge that will pass through the cross-section of the conduction in 30 s. How many electrons will flow in this time interval? (Charge on an electron, e = 1.6 $\times$ $10^{- 19}$ C)

Open in App

Solution

Amount of charge = 0.2 $\times$ 30s = 6C

Number of electrons = $\frac{0.6}{1.6 \times 10^{- 19}}$ = 37.5 $\times$ $10^{17}$
