- • e = 1.6 * 10-19 Coulombs
- • current I = 0.2 Amperes .
- time duration t= 30 seconds
Charge = Q = current * time duration = [* t = 0.2 sec * 30 sec =6 coulombs
number of electrons that are equal to this charge = 6 Coulombs / 1.6 * 10-19 coulombs
= 3.75 * 1019
If this many electrons pass through a cross section of the conductor in 30 seconds time
