What is the actual current direction of the composite tube?
The direction of the positive charge is the direction of the current. Now the continuation of the statement. In fact, in metal conductors, it is free to move negatively charged, that is, electrons.
Composite tube: in a shell of an electron tube, there are more than two electrode systems, each electrode system independently through the electronic flow to achieve their respective functions, this tube is called a composite tube. A composite tube is a combination of two or more transistors in accordance with a certain law, which is equivalent to a triode, and the compound tube is also called a Darlington tube
At that time, in the electrolyte, the positive and negative charges were moving, only in the opposite direction of the directional movement. In semiconductors, some of them move with positive charges, and some of them move negatively.Also, the current is scalar, i.e., without direction. The direction of the current is only a rule of thought.
