Answer:
Charge = 3.2 × 10^-22 Coulomb
Electric Current = 0.9 × 10^-22 Ampere
Explanation:
Since, Charge = No. of electrons × charge on an electrons
Therefore,
Charge = 2000×(1.6×10^-19)
Charge = 3200.0×10^-19
Charge = 3.2 × 10^-22 C
Now, Electric Current = Charge/Time
Therefore,
Electric Current
=( 3.2×10^-22)/4
=0.9×10^-22 A
