1.	A current of 0.43 A is flowing through a wire of thickness 2 cm. If there are 1018 electrons per cm3 of the wire, calculate the drift velocity of electrons in ms−1. Take the electron charge as 1.6×10−19 C.
Answer» A current of $0.43 A$ is flowing through a wire of thickness $2 c m$ . If there are $10^{18}$ electrons per $c m^{3}$ of the wire, calculate the drift velocity of electrons in $m s^{- 1}$ . Take the electron charge as $1.6 \times 10^{- 19} C$ .
