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
The inputs to an SRFF are shown in Figure. Determine the value of Q at times t 1 , t 2 , and t 3 .
What do you understand by DRAM and its refreshing? Dynamic RAM (DRAM) is fundamentally the same as SRAM, but this retains data for only 2 or 4 ms on an internal capacitor. But
Verify the minimum & maximum load current for which the zener diode will keep regulation. Find the minimum value of RL that can be used. The zener diode has V Z = 12V, I ZK =
What is the use of basic earth-sun angles? Show by mean of diagram. Illustrate sun as source of energy with relevant data? Illustrate flat plate collectors. Describe liquid f
Q. The current through a 2.5-mH indicator is a damped sine given by i(t) = 10 e -500t sin 2000t. With the aid of MATLAB, plot the waveforms of the inductor current i(t), with v
When I read the details of how a transformer works and apply those rules to a transformer where the primary core cross-sectional area is twice that of the secondary, I come up with
Energy Conservation Our country has a vast potential of energy saving. It is estimated in which measures for energy conservation and improving energy efficiency have the pote
Q. Find the parameter values V T and I DSS for a p- channel MOSFET with i D = 0 when v GS ≤-3 V, and i D = 5 mA when v GS = v DS =-8V.You may neglect the effect of v DS on
