An ac LVDT has the following data; input 6.3V, output 5.2V, range ±0.50 cm. Determine: a) Plot of output voltage versus core position for a core movement going from +0.45cm to -0.03cm? b) The output voltage when the core is -0.35cm from the center? c) The core movement from center when the output voltage is -3V? d) The plot of core position versus output voltages varying from +4V to -2.5V.

How about solving this using KCL equations? Thank you

Question 3: If the currents are in the same direction for a pair of parallel running wires, the currents on the wires are referred as Common Mode currents, ICM. On the other hand, if one of the currents is running in reverse direction (as they should normally do), the currents are referred as Differential Mode currents, IDM. It is essential in analog circuit design to keep track of differential and common mode currents. Referring to the following illustrations, assume that the separation between the wires, d, is 4 mm, the magnetic field observation point, S, is 20 mm away from the right wire, ICM- 5 mA, and IDM= 150 mA.
