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.
Q. Illustrate Transformer coupling? In this method the primary winding of the transformer acts as a collector load and the secondary winding transfers the a.c. output signal di
Q. A transformer is rated 10 kVA, 220:110 V (rms). Consider it an ideal transformer. (a) Compute the turns ratio and the winding current ratings. (b) If a 2-load resistance
Q. A silicon BJT has an emitter current of 5m Aat 300 K when the BEJ is forward-biased by vBE = 0.7 V. Find the reverse saturation current of the BEJ. Neglecting ICBO, calculate iC
