Is" positive charge -high electric fluid and negative charge-low electric fluid " correct ??
If it is correct, then is electric current in a circuit, the movement of this electric fluid from positive terminal to negative terminal of the cell??
If this is true , then when equilibrium is reached will the current flowing in the circuit stop automatically ??
An electric current is a flow of electric charge. In electric circuits this charge is often carried by moving electrons in a wire. It can also be carried by ions in an electrolyte, or by both ions and electrons such as in an ionised gas (plasma).
Direction of current is always consider as the opposite flow of charge(electron).
Generally speaking it is not considered as fluid that flow, here it means the electron is moving by the word "flow"
But However there is a theory proposed
Fluid theories of electricity are outdated theories that postulated one or more electrical fluids which were thought to be responsible for many electrical phenomena in the history of electromagnetism.
The "two-fluid" theory of electricity, created by Charles François de Cisternay du Fay, postulated that electricity was the interaction between two electrical 'fluids.' An alternate simpler theory was proposed by Benjamin Franklin, called the unitary, or one-fluid theory.
This theory claimed that electricity was really one fluid, which could be present in excess, or absent from a body, thus explaining its electrical charge.
The fluid theories of electricity eventually became updated to include the effects of magnetism, and electrons (upon their discovery).
