The direction of conventional current flowing in an electric circuit is always from
Correct answer: B. positive to negative terminals only.
- A. negative to positive terminals only.
- B. positive to negative terminals only.
- C. negative to positive terminals and vice versa.
- D. positive to negative terminals and vice versa.
Explanation
The correct answer is Option B: positive to negative terminals only. Conventional current flow in an electric circuit is defined as the flow of positive charge from the positive terminal of a voltage source to the negative terminal. This direction was established before the discovery of the electron and is still used to represent current flow. The other options are incorrect because they do not align with the conventional current flow direction.

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.
