Use a 2N7002 MOSFET, connect the source to ground and add separate DC voltage sources to the gate and drain. Set the voltages to 2.5 V (gate) and 5 V (drain). Save an image of your circuit and include it in your document. Perform a dc operating point (DC op pnt) simulation and paste the output (as text) in your document. Confirm that the operating point is at approximately VGS = 2.5 V and ID = 62 mA. [3 marks]...

Problem: A PM DC motor has the following parameters: Rated Power 10 hp; Rated armature voltage 230 V-DC; Rated RPM: 1800; Armature Resistance: 0.2 Ohm Armature Inductance: 0.005 H Inertia (motor plus mechanical load): 0.1 kgm^2; Viscous friction coefficient: 0.015 Nms 1. Compute the voltage constant of the motor. Also compute the rated current and rated torque of the motor (obtained at the rated RPM). If the motor is supplied by 230 V across the armature, and the only torque...
