WHY SOURCE (S) AND DRAIN (D) OF A MOSFET MIGHT BE CONNECTED TOGETHER?

Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFETs) are indispensable components in modern electronic circuits. The connection between the source (S) and drain (D) terminals plays a critical role in the proper operation of the circuit. Under normal circumstances, the source and drain are connected via external circuitry, but there are situ
