Plz solve question 1 and 2

Plz solve question 1 and 2 RICALS a conductor, 6•25 x 1016 electrons flow from its end A to B in 2 s. Find the current flowing through the conductor. (e = x 10-19 C) Ans. 5 mA from B to A 2. A current of 1 •6 mA flows through a conductor. If — x 10-19 coulomb, find charge on an electron IS the number of electrons that will pass each second through the cross section of that conductor. Ans. 1016 3. Find the potential difference required to flow a
