Emitter, collector and base In its essence, a transistor consists of two diodes arranged back to back: Transistors can be either n-p-n or p-n-p. The configuration shown above is called an n-p-n transistor. The terminal on the left is called the emitter, the terminal on the right is

WebMar 11, 2024 · A transistor either works as a switch or as an Amplifier. How It works It takes a tiny electrical current at one end (an input current) when it acts as an amplifier, and generates a much greater electrical current (an output current) at the other. Kind of like a current booster, for lack of a better word. WebThe drain voltage is superposition of DC and AC voltages: V D = V D C + v A C, where V D C is obviously 12 V and v A C is G ∗ v I n. Given the transistor gain G >> 1, the drain voltage swings about 12V, so its amplitude is definitely higher than 12V. But how can it be if the power source dictates the 12V limit?? WebBipolar Junction Transistors, or BJT's, have been around for decades and was and are a fundamental portion of modern electronics and computing. For somethin... green-winged teal images
