Conventional current flows from which terminal to which in a circuit diagram?

Conventional current flows from which terminal to which in a circuit diagram?

• A. From the positive side of the battery to the negative side. This is the way current is drawn in circuit diagrams, even though it is wrong.
• B. From the negative side to the positive side.
• C. Along with the electron flow from negative to positive.
• D. In the direction of the magnetic field in the circuit.

Answer: (A)

Conventional current is defined as the flow of positive charge from higher electric potential to lower potential. In a simple circuit, that means current is considered to leave the positive terminal of the battery, pass through the components, and return to the negative terminal. In metal wires, the actual moving charge carriers are electrons, which are negative and move from the negative terminal toward the positive terminal, opposite to the conventional current direction. The magnetic field aspect isn’t about the direction of current flow in diagrams; it’s a separate effect that relates to how current creates magnetic fields. So the standard depiction of current in diagrams is from the positive end to the negative end.
