**Which Type of Current Flows from Positive to Negative?**
Understanding Electric Current
Electric current is a fundamental concept in physics that has been studied for centuries. It is the flow of electric charge, typically measured in amperes (A). However, there are different types of electric current, and understanding the differences between them is crucial for anyone interested in physics.
Types of Electric Current
There are two main types of electric current: conventional current and electron flow. Conventional current is the type of current that flows from positive to negative, while electron flow is the type of current that flows from negative to positive.
Conventional Current
Conventional current is the type of current that was first described by Benjamin Franklin in the 18th century. It is the type of current that flows from positive to negative, and it is the type of current that is commonly used in electrical circuits. Conventional current is often referred to as "positive current" because it flows from the positive terminal of a battery to the negative terminal.
Electron Flow
Electron flow, on the other hand, is the type of current that flows from negative to positive. It is the type of current that is carried by electrons, which are negatively charged particles. Electron flow is often referred to as "negative current" because it flows from the negative terminal of a battery to the positive terminal.
Key Differences
There are several key differences between conventional current and electron flow. The most significant difference is the direction of the current flow. Conventional current flows from positive to negative, while electron flow flows from negative to positive.
Ampere and Resistance
Ampere (A) is the unit of measurement for electric current, and it is defined as the flow of one coulomb of charge per second. Resistance, on the other hand, is the opposition to the flow of electric current, and it is measured in ohms (Ω).
Static Current
Static current is not a type of electric current, but rather a term used to describe a situation where there is no flow of electric charge. In other words, static current is the absence of electric current.
Direct Current
Direct current (DC) is a type of electric current that flows in one direction only. It is the type of current that is produced by a battery or a generator, and it is commonly used in electrical circuits.
