A sensitive thermometer produces a voltage that changes 10 mV for every degree change in temperature.
If the signal is connected to the input of an inverting op-amp circuit, what voltage gain is necessary so that the output of the amplifier produces a change of 2 V for every degree change in temperature?
A current element of length 1cm is located at (1m, 3m, 4m) in free space and carries a current of 20mA along ay. An infinitely long filamentary current of 12A along az passes through the coordinate origin (0,0).
The response of a first order series RL circuit can be represented by a first order linear time-invariant differential equation : d/dt(y) + 4 y= 4 x(t) where the input x(t) is applied across the series circuit and the output is across the resistor
The voltage on bus 1 is 1.0 per unit (pu) at 30 degrees; the voltage on bus 2 is 0.95 per unit at 5 degrees. The reactance connecting bus 1 to bus 2 is 0.5 per unit Ohms, and the resistance is negligible. a)How much real power (pu) is flowing from ..
Inverse Z-transform and poles and zeros. When finding the inverse Z-transform of functions with z-1 terms in the numerator, the fact that z-1 can be thought of as a delay operator can be used to simplify the computation.
Some of this is due to high frequency effects, and some is due to the relationship of the wavelength of the signal being set over the wire to the length of the conductor. describe both of these limitations and their effects
A 25 MVA, three phase, 13.5kV, Y-connected, two pole, 60 Hz synchronous generator was tested by the open circuit test and short circuit test and tabulated in table 1. If the armature resistance is 0.24 ohms per phase
What is the main operation when a comparator cascade with an active third order low pass filter, with a feedback of output to input.
A proportional control system is to be used to control the wing flaps of a jet air-plane. The wind load is expected to cause as much as 600 in .lb of torque. The system should be able to keep the flaps to within 5 of the set point.
Built-in voltage for a Si p-n junction is tested to be 0.6 V, NA = 2 X 10^15 cm^-3 on p side. Find ND on n side. (Assume ni = 1 x 10^10 cm^-3; and k*T/q= 0.026 V)
(a) Compute the minimum voltage that the output voltage across R1 falls to when both capacitors C1 and C2 are present. (b) Using the same model for D1, compute the maximum voltage that the output voltage across R1 rises to.
The resistance of the filament of the bulb, measured with a standard multimeter, is 16.7 ohms. When the bulb is connected into the circuit and is operating at the rated values given above determine a) the resistance of the filament b) the efficien..
The Russian president and the Chinese counterpart need to come to an agreement by telephone. Neither can speak and understand each other's language. They need to employ translators. Compare this layered communication to OSI layers.
