Why do the particles flow from the negative terminal to the positive terminal?

The particles are electrons and they go that way because they are negatively charged. That was discovered after electric circuit theory was developed, it was formerly assumed that the charge goes from + to -. That's why it seems it goes the wrong way.

Do electrons come out of the negative or positive terminal?
Electrons are negatively-charged particles that flow out from the negative terminal and into the positive terminal of a battery. It was once assumed that moving particles had a positivecharge, and so this conventional current flow set the original arrow direction, still shown on diodes and junction transistors.
Do electrons flow from the positive to the negative terminal of a wet cell?
Electrons have a negative charge. For that reason, electrons will always flow in the opposite direction of the current, which flows from positive to negative. Electrons will therefore move from a negative terminal to a positive terminal when we look at the load on a cell. Within the cell, the electrons will flow from the positive terminal to the negative terminal.
What end does electrons flow in a circuit?
the positive side, the negative side is usually just a ground
Why electrons flow in negative to positive direction?
Electrons are negatively charged particles. The reason the negative side of your D battery is negative is because that's where the free electrons are. The positive terminal is starved or has a deficit of electrons. The negatively charged electrons naturally want to fill the 'holes', in atoms lacking an electron on the positive side. Thus electron flow is from negative to positive. Conventional current flow assumes that current flows out of the positive terminal, through the circuit and into the negative terminal of the source. This was the convention chosen during the discovery of electricity. They were wrong!
Why is it necessary that an electron returns to the positive terminal of the battery each time another electron leaves the negative terminal?
Electrons are negatively charged, and so are attracted to the positive end of a battery and repelled by the negative end. So when the battery is hooked up to something that lets the electrons flow through it, they flow from negative to positive.

The flow of current in electrodes is in which direction?
The ELECTRONS flow from the negative to the positive terminal. But it is considered that the electric current flows from the positive to the negative terminal.
What direction will an electric current flow?
from positive terminal to negative terminal
What is the positive terminal of a diode known as?
It is called the positive + terminal or post, just like you list. Electrons flow for the negative - to the + terminal contrary to popular belief.Another AnswerAs electrons flow through the external circuit from anode (negative terminal) to the cathode (positive terminal) , then the answer is 'cathode'.
How you can indicate the current direction in the network?
If we go for the diagramatic representation then battery positive is represented by the long terminal and battery negative is represented by the short terminal then the direction of the current is given by an arrow from positive terminal to negative terminal (Therotically electrons flow from negative to positive but we represent current flow from positive to negative. This is the sign convention )
What is the positive terminal of the battery called?

Where does the electricity come out of a battery?
The electricity flows out the negative terminal, through the work load, and back into the positive terminal. It consists of negative electrons. In the early days of electrical experimenting, the scientists had to guess as to whether the electric flow was positive particles or negative particles. They had no way to test. They guessed positive. They were wrong. So we have inherited a definition of current as positive fluid going from positive terminal (outside the battery now) to negative terminal. We have stayed with that convention even though we know better today. It makes no difference at the circuit level. Positive particles flowing rightward has the same effect as negative particles flowing leftward. Of course, if you are designing batteries, you will want to know what flows which way.
What end does electrons flow in a circuit?
the positive side, the negative side is usually just a ground
How does current flow along a conductor?
Conventional Current states that current moves from the positive terminal of a power supply to the negative terminal.Electron Flow states that electrons move from the negative terminal of a power supply to the positive terminal.
A grounding wire allows the movement of electrons in which direction?
Electrons flow from the negative terminal to the positive. Conventional current or simply current, behaves as if positive charge carriers cause current flow. Conventional current flows from the positive terminal to the negative
What does the positive side of the battery do?
When connected to the cable which normally runs to the starter it completes the circuit. Electrons flow from the negative terminal to the positive terminal.
