			Point-Contact Circuit If we introduce the transistor in a circuit, such as the one in the picture, you can see that all three terminals are connected. We can think of the left and the right half of the circuit as two separate parts, although they are physically connected to each other in reality. Each of these halves has characteristics similar to the diode that we described previously.
