Quizplus · Accepted Answer

With the source terminal grounded, the drain voltage VD is determined by the voltage drop across the load resistor connected from the drain to the supply voltage. Assuming the transistor is in saturation and acts as a switch, it effectively connects the drain to the source (ground) when on, leading to minimal voltage at the drain. However, without specific details on the transistor operation from the figure, the most likely scenario given typical transistor operation characteristics and assuming some voltage drop due to not being an ideal switch, is that the drain voltage would be close to the supply voltage minus any voltage drop across the transistor, leading to an approximation rather than an exact science without the figure details.
