Q. For the mechanical spring-mass-friction system shown in Figure, the differential equation relating the force F(t) and the velocity u(t) is given by
where M is themass,Dis the friction, and Cm is the compliance (reciprocal of stiffness) of the spring. For M = 20 kg, D = 4 kg/s, and Cm = 8 N/m,
develop an electric equivalent network (a) using the force-current analog, and (b) using the force- voltage analog, and find u(t) for F(t) = 40e-t/4 N.

What is Permeability? Permeability: This is defined as the ability of the material to conduct flux. This is defined as the ratio of magnetic flux 'B' in a medium to the magneti
Q. Illustrate Core Losses in magnetic core material? Iron-core losses are usually divided into two components: hysteresis loss and eddy-current loss. The former is proportional
Two pure sine waves have similar amplitude "A" and frequency "f." They are out of phase through 180 degrees. If these two signals are added, the resulting waveform will be:
