![]() ![]() In this article, current arrows are shown in the conventional direction, but labels for the movement of holes and electrons show their actual direction inside the transistor. On the other hand, inside a bipolar transistor, currents can be composed of both positively charged holes and negatively charged electrons. ![]() However, current in many metal conductors is due to the flow of electrons which, because they carry a negative charge, move in the direction opposite to conventional current. 4.1 Active-mode transistors in circuitsīy convention, the direction of current on diagrams is shown as the direction that a positive charge would move.2.3 Transistor parameters: alpha (α) and beta (β).2.2 Turn-on, turn-off, and storage delay.2.1 Voltage, current, and charge control.
