#Transistor amplifier series#

One of the transistors is connected so that it controls the current to the base of the other transistor. The basic Darlington transistor circuit is formed from two bipolar transistors wired emitter to base so they act as one transistor. The 'B' stands for base, the 'C' stands for collector, and the 'E' stands for emitter. The circuit symbol of a Darlington transistor. The water is the electrons, and when you positively charge the gate, it unbends the hose, letting water flow. The transistor can also work when the gate is just positively charged, so it doesn't need to be touching the drain.ДЄn easy way to think of how a transistor works is as a hose with a sharp bend that stops the water from going through. This is because when the gate is positively charged, the positive electrons will push other positive electrons in the transistor letting the negative electrons flow through. But when power flows through the gate (or base), the transistor will allow electricity through.

When the source (or emitter) is connected to the negative terminal of the battery, and the drain (or collector) to the positive terminal, no electricity will flow in the circuit (if you have only a lamp in series with the transistor). Transistors have three terminals: the gate, the drain, and the source (on a bipolar transistor, the wires can be called the emitter, the collector, and the base). When the center pin is powered, the power can flow.
