Question

if 15 electron passes through a conductor in 0.03 minutes find the electric current through it​

Answer 1

charge carried by one electron =1.60 × 10-19
charge carried by 15 electrons = 15 x 1.60× 10-19
be. =24× 10-19
So, Q(charge)= 24 × 10-19 coulumb
Time = 0.03 minutes--------- or 1.8 seconds
l =current
•••••> I =Q / T
•••••> I = 24× 10-19/1.8
•••••>
$i = 1.33 \times {10}^{ - 18} ampere$
best of luck
