Differences between UJT and FET. ujt (transistor at a junction): it is a transistor with a single junction and three terminals: a transmitter (e) and two bases (b1 and b2).
How is FET a voltage controlled device? the voltage applied between the gate and the source controls the drain current (id). which means you use the voltage to control the
Why do we limit FET operation to small signals? The materials used in the construction of the transistor layers are not designed for high amperage, voltages or frequencies. line currents
