A drilling machine is driven by a single-phase induction motor connected to a 110-V rms supply. Suppose that the machining operation requires 1 kW, that the tool machine ihas 90 percent efficiency, and that the supply current is 14 A rms with a power factor of 0.8. Find the AC machine efficiency.
A saturated npn transistor has a base to emitter applied voltage of 0.6V. The collector to emitter voltage is 0.2V. The collector current is 12mA
A control system for positioning the head of a floppy disk drive has the closed-loop transfer function T(s)=11.1(s+18) / (s+20)(s^2+4s+10). Plot the poles and zeros of this system and discuss the dominance of the complex poles.
Finding peak amplitude, frequency, and spectrum shape, b. A signal generator outputs a unipolar square wave with a period of 0.50 ms and an amplitude of 2.0 V. The output of the generator is passed through an ideal band pass filter that has a pass..
At a point f in the system, there is an open-circuit fault on phase-a with a voltage across the open-circuit as Vfa , whereas Vfb =Vfc =0. Similar to the calculations of the short-circuit currents by making use of the sequence networks
In transformer designs, often you can find an air gap in the core. In all the electric machines, there is an air gap between the stator and rotor. In both cases, flux will go through both core material and the air gap.
If the U.S. consumes 10 Quads each year by burning gasoline for automobiles, and if this energy usage is spread evenly across 8760 hours in a year, what is the equivalent continuous flow of power in Megawatts (MW)
The following specification s are given for fours different temperature sensors. If the application requires a temperature variation of -50°C to 120°C and the measured value is -20°C, select the best sensor.
