The direction of electric current - Mystery solved! - Electrical …
In terms of circuit analysis, we normally consider the direction of electric current from positive to negative. Mathematically, negative charge flowing in one direction is equivalent to positive charges flowing in the opposite direction.
Electric current - Wikipedia
The conventional direction of current, also known as conventional current, [ 10 ][ 11 ] is arbitrarily defined as the direction in which positive charges flow. In a conductive material, the moving charged particles that constitute the electric current are called charge carriers.
9.2: Electrical Current - Physics LibreTexts
The rate at which the charges flow past a location—that is, the amount of charge per unit time—is known as the electrical current. When charges flow through a medium, the current depends on the voltage applied, the material through which the charges flow, and the state of the material.
20.1: Current - Physics LibreTexts
The direction of conventional current is the direction that positive charge would flow. Depending on the situation, positive charges, negative charges, or both may move. In metal wires, for example, current is carried by electrons—that is, negative charges move.
Conventional current direction - Khan Academy
The direction of current does matter. 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.

Physics Tutorial: Electric Current - The Physics Classroom
The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery.
9.1 Electrical Current - University Physics Volume 2 - OpenStax
Describe an electrical current. Define the unit of electrical current. Explain the direction of current flow. Up to now, we have considered primarily static charges. When charges did move, they were accelerated in response to an electrical field created by a voltage difference.
Electric Current – definition, equation, types and direction
2022年10月28日 · What is the conventional direction of electric current? Current is not a vector quantity, it’s a scalar. Still, it has a direction. The conventional direction of current flow is along the direction of the motion of positive charges. In most cases, …
2.1.2: Conventional Current Flow and Electron Flow
2024年1月23日 · Before we dive into series circuits we need to revisit an interesting question involving the direction of current flow. Does it flow from positive to negative or from negative to positive? Why do we define the direction of current as the positive charge flow direction?
