A residential four-wire system supplies power at 220V rms to the following single-phase appliances: On the first phase, there are ten 75-W bulbs. On the second phase, there is a 750-W vacuum cleaner with a power factor of 0.87. On the third phase, there are ten 40-W fluorescent lamps with power factor of 0.64.
Find (a) The current in the neutral wire. (b) The real, reactive, and apparent power for each phase.
A 4800/480 volt, single phase transformer is rated at 75KVA. test results performed for rated power showed the following. short circuit test V=80v, P= 2470W, I= Rated current open circuit test V= 480v, I=4Amp, P=616W
how the amplifiers should be connected. To proceed, evaluate the two possible connections between source S and load L, namely, SABL and SBAL. Find the voltage gain for each both as a ratio and in decibels. Which amplifier arrangement is best
Determine the panel orientation you would choose to obtain maximum energy: (a) Over the year (b) In the summer (c) In the winter Discuss your choice of slope angles if the location is at 75°N.
Include the unused states in the design, arranging the circuit to switch from any unused state to the 'main sequence' within one clock cycle, and show the state diagram that applies here. Clearly show all the steps of the design procedure used.
Basics problems of Induction motor, The frequency of the induced rotor currents in the rotor of a 60 Hz induction, machine is 2 Hz. Furthermore, the fields in the air gap turn at -40 rpm with respect to the rotor.
Finding values of a composite discrete time signal, A discrete time signal x(n) = x(n-1) + x(n-3) with initial conditions x(0) = 0, x(1) = 1 and x(2) = 2 is examined and the first 51
