A single-phase source is connected to an electric load. The load draws a 0.6 oer-unit current at 1.10 per-unit voltage while taking real power of 0.5 per-unit at a lagging power factor. Choose a base voltage of 12.47KV and a current of 100A. Calculate the following:
a Real power in KW
b Reactive power in KVAR
c Power factor
d The ohmic values of the resistance and reactance of the load
any noise will pass straight through to the ADC subsystem, introducing measurement error. You have two choices to mitigate this: SW filtering and HW filtering. Either way around, you need a HW anti-aliasing (low pass) filter following the output.
Based on these equations, determine the maximum power point. This is the value of and T that result in maximum power. State the power and the (,T) values. Do not assume this happens at 0.5T. The best way to do this is to make an Excel spreadsheet.
First you must give all different possible connection types for them and then, for each case, you should develop some tests that can define the connection type and calculate the current passing through the capacitors.
Suppose the information portion of a packet contains 10 bytes consisting of the 8- bit unsigned binary ASCII representation of string "Link Layer".
A four pole DC machine has a wave winding of 300 turns. The flux per pole is .025 webers. The DC machine rotates at 1000 RPM. Determine the generated voltage and the kW rating if the current through the turn is 25 amps.
A noninverting amplifier has a closed loop voltage gain of 11. What is the output peak voltage if the input is 2 V peak to peak?
A 115/28 V transformer has 56 turns on its low voltage side. How many turns does it have on its high voltage side what is its turns ratio when it is used as a step-down transformer
To put this number into perspective, on June 20, 2002 the US national debt was $6.1e12, which is about $21,000 for each of the 288 million US citizens. What number when multiplied by the US national debt equals the cost to toast the bread.
A lossless line having an air dielectric has a characteristic impedance of 100 Ohms. Another line that is identical in dimensions to the air line is fabricated with the air displaced by a dielectric material have an \(\epsilon_{r}\) value of 4.
The electric field in a region of space is E= 4 ax V/m and the magnetic flux density is B= 5 az Wb/m2. At t= 0 a particle with mass 1 kg and charge 1 C is located at the origin traveling at a velocity of u0= 10 ay m/s.
A silicon sample at T = 300 K contains an acceptor impurity concentration of \(N_{A}\) = 1016 cm-3. Determine the concentration of donor impurity atoms that must be added so that the silicon is n-type and the Fermi energy is 0.20 eV
What kind of transistor has higher voltage gain, BJT or FET and why What kind of transistor has better noise response BJT or FET and why How about frequency response high frequency, FET or BJT Low frequency response, FET or BJT
