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
imin =( ?KT/ TRc)1/2
I have all my report about Vehicle suspension systems . But I need the simulation and hardware test for this project. I need you to do it and give me the observation.
Q. A three-phase load, connected to a 440-V bus, draws 120 kWat a power factor of 0.85 lagging. In parallel with this load is a three-phase capacitor bank that is rated 50 kVAR . D
