Q. Working of Field-effect transistors?
Field-effect transistors (FETs) may be classified as JFETs (junction field-effect transistors), depletion MOSFETs (metal-oxide-semiconductor field-effect transistors), and enhancement MOSFETs. Each of these classifications features a semiconductor channel of either n-type or p-type, whose conduction is controlled by a field effect. Consequently, all FETs behave in a similar fashion. The FET classification is illustrated in Figure along with the corresponding circuit symbols. FETs have the useful property that very little current flows through their input (gate) terminals.
Q. Explain the working of Rectifier Circuits? A simple half-wave rectifier using an ideal diode is shown in Figure(a). The sinusoidal source voltage v S is shown in Figure (b)
Explain Stator of a Synchronous Machine? The stator of a synchronous machine is made of thin laminations of highly permeable (silicon) steel in order to reduce the core losses.
