A factory has an electrical load of 1,800kW at a lagging power factor of 0.6. An additional variable power factor load is to be added to the factory. The new loaf will add 600kW to the real power load of the factory. The power factor of the added load is to be adjusted so that the overall power factor of the factory is 0.96 lagging. The factory is fed from a line having an impedance of 0.02 + j0.16 O. The voltage at the factory is maintained at 480 V(rms). Find the average power loss in the line before and after the load is added. Find the magnitude of the voltage at the sending end of the line before and after the load is added.
A DC source of 48V is connected to one end of the cable. The other end of the cable supplies a DC load. If the load current is 12.5 A, calculate the voltage drop due to the cable resistance and the laod voltage.
Use Smith Chart: A 100 Ohm air-coaxial transmission line is measured to have an input impedance of 100 + j100 Ohms. If the system is operated at 100 MHz and is one meter long, what is the terminating load impedance
There are three gates. Each gate can be opened or closed depending on the three logic inputs: (a, b, c). Gate open logic=1, gate close= logic 0. Design a logic circuit so that no adjacent gates or outputs (x, y, z) are open at the same time.
You are lowering two boxes, one on top of the other, down the ramp shown in the figure by pulling on a rope parallel to the surface of the ramp. Both boxes move together at a constant speed of 16cm/s.
Power factor improvement, An industrial user has a number of machine tools which are driven by three phase induction motors. during a particular shift, the power factor of the combined load can vary between 0.65(100 KVA load) and 0.81 (20 KVA) loa..
An amplifier has a gain Ad,dB = 40 dB. Its common-mode rejection ratio is CMRRdB= 120 dB. It is used to amplify an input which has a 200mV desired signal along with an undesired common-mode signal ("noise").
Four signals, each having W = 3 kHz, are to be frequency-division multiplexed with 1-kHz guard bands between channels. The subcarrier modulation (modulation to accomplish the FDM) is AM, with one signal left at baseband.
A 22KVA, 2300/230 VAC, 60HZ transformer is tested with a short circuit test. The measured data are as follows: Psc=280W, Vsc=80VAC and Isc=9.5 A 1. Find the transformer turns ratio of the transformer
A continuos-time system is given as a differential equation: y''(t)+2y'(t)+3y(t)=x'(t)+x(t-2) a. Compute the Transfer function H(s) of the system. b. Compute the Impulse Response h(t). c. Compute the Step Response g(t).
Calculate: Critical frequency for the input low pass network, and the output low pass network, estimate the values for Cbe, Cjc, Cbc, and Cje. Concider the resistance of the signal sourceRs to be equal to the 1 ohm resister in series with the source.
very useful not only in obtaining the rectangular and polar forms of complex numbers
if a circuit contains 3 automatic switches and we want that, with a probability of 95%, during a given time interval they are all working, what probability of failure per time interval can we admit for a single switch
