Here the current flow due to positive charges. Positive charges flow from positive terminal to negative terminal. In general, analyzing an electrical circuit yields results that are independent of the assumed direction of current flow. Conventional current flow is the standard that almost all of the world follows to solve a circuit problem. [wp ...
In conventional flow notation, we show the motion of charge according to the (technically incorrect) labels of + and -. This way the labels make sense, but the direction of charge flow is incorrect. In electron flow notation, we follow the actual motion of electrons in the circuit, but the + and - labels seem backward.

What is the difference between conventional current and negative current?
The idea of 'conventional current' has kind of a quirky definition, it's the direction positive charge would move. It happens that electrons move in the opposite direction of the conventional current arrow. That doesn't mean we don't care which way current flows, it just means our definition of positive current is a little unexpected.

Feb 20, 2022 · Figure 20.1.3 20.1. 3: Current I I is the rate at which charge moves through an area A A, such as the cross-section of a wire. Conventional current is defined to move in the direction of the electric field. (a) Positive charges move in the direction of the electric field and the same direction as conventional current.
Jan 23, 2024 · Today we call this idea conventional current flow. In this model, current flows from a more positive voltage to a less positive voltage. We know now that the electron is the charge carrier in metals and the electrons travel in the reverse direction. Essentially, Franklin guessed wrong. Electrons move from a lower potential to a higher potential.
To provide a definition of current independent of the type of charge carriers, conventional current is defined as moving in the same direction as the positive charge flow. So, in metals where the charge carriers (electrons) are negative, conventional current is in the opposite direction to the overall electron movement.
