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
Q. At the two terminals (A, B) of a one-port network, the voltage and the current are given to be v(t) =200 √2 cos (377t + 60°) V and i(t) = 10√2 cos(377t + 30°) A. (a) Determin
Explain Load Flow Analysis The method commonly used for load flow analysis is the nodal analysis. The nodal analysis method is given in many books on circuit theory and is base
Explain In brief about the Robots - Robot is programmed with a series of instructions that enable it to carry out a series of tasks - On the other hand, an operator manually
Dielectric materials are (A) Insulating materials. (B) Semiconducting materials. (C) Magnetic materials. (D) Ferroelectric materials. Ans:
Determine the node voltage: Determine the node voltage V and then current flowing through each element by using KCL. Solution Apply KCL at the node whose voltage is V.
Q. Show Maximum Power Transfer? In order to investigate the power transfer between a practical source and a load connected to it, let us consider Figure , in which a constant v
Antenna Fundamentals We shall discuss here only the fundamental concepts needed to understand the role of an antenna as a power-coupling element of a system. Figure illustrates
.
Since dc motors of various types are used extensively in control systems, it is essential for analytical purposes that we establish a mathematical model for the dc motor. Let us co
Q. The N-coil windings of a three-phase, two-pole machine are supplied with currents ia,ib, and ic, which producemmfs given by F a = Ni a cos θm; F b = Ni b cos(θm - 120°); and
