A moving coil galvanometer consists of a coil in a uniform magnetic field Bo, suspended fro a fibre of torque constant C, current I produces a deflection O=nABoi/c where n is the number of turns and A is the area of the coil. The period of oscillation T=2?(I/C)1/2 where I is the moment of inertia. The resistance of the coil and the circuit in which it is placed is adjusted to give a critical dumping Rc=n2 A2Bo2/2(ic)1/2 . if the minimum detectable current produces deflection equal to thermal -root mean square value O, show that minimum current is given by

Explain the Synchronous Compensators These are synchronous motors running without mechanical loads (or with load if required). Similar to the synchronous generators, they can a
Q. Given that a silicon n-channel JFET has V P = 5 V and I DSS = 12 mA, check whether the device is operating in the ohmic or active region when v GS =-3.2 V and i D = 0.5 mA.
