If two electrons are passing across a point in 2 seconds then the current following will be:
Correct answer: D. 1.6 x 10^-19 amperes
- A. One ampere
- B. Two ampere
- C. 1.6x 10+19 amperes
- D. 1.6 x 10^-19 amperes
Explanation
I = Q/t = Ne/t = 2 x 1.6 x 10-19 / 2 = 1.6 x 10-19 A. Therefore, D is the correct answer.

About Steady Current
Steady current is the continuous flow of charge at a constant rate through a conductor. The topic covers current, charge, potential difference, resistance, Ohm's law, resistivity and electrical power, along with series and parallel circuits, while distinguishing conventional current direction from electron motion.
