WebbTo understand it we must understand how current flows. Let’s say you have one small voltage and one big voltage. Current will flow from Big Voltage to Small Voltage. Now the current flows properly in a good circuit. Here comes the open circuit. Where your circuit is not properly configured and is incomplete. Here our current has no way to ... WebbA small current flow is established in this channel to set up internal voltage drops that are the key to the operation of the UJT. Diffused into the channel is a heavily doped p-type region known as the ‘emitter’. It provides the current carriers for the current pulse produced by a UJT. The construction and graphical symbol are shown in Figure 1.
