The equivalent current which passes from a point at higher potential to a point at a lower potential as if it represented a movement of positive charges is:
Correct answer: D. Conventional current
- A. Electronic current
- B. Electric current
- C. Magnetic lines
- D. Conventional current
Explanation
The correct answer is D: Conventional current. Conventional current is defined by the direction in which positive charges would flow, from higher to lower potential, which is opposite to the actual direction of electron flow. Option A is incorrect because electronic current describes electron flow, which goes from low to high potential. Option B is incorrect because, while electric current involves the movement of electrons, it does not specify the direction of conventional current. Option C is incorrect because magnetic lines are unrelated to electric current flow.

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.
