Q. Three single-phase 100-kVA, 2400:240-V, 60-Hz transformers (each ofwhich has an equivalent series impedance of 0.045+j0.16 referred to its low-voltage side) are connected to form a three phase, 4160:240-V transformer bank, which in turn is connected to a three-phase feeder with an impedance of 0.5 + j1.5 /phase. When the three-phase transformer bank delivers 250 kWat 240Vand 0.866 lagging power factor, determine:
(a) The transformer winding currents.
(b) The sending-end voltage (line to line) at the source.
can voltage regulation be negative?why?

Q. Briefly explain about Wye-delta transformation? Certain network configurations cannot be reduced or simplified by series-parallel combinations alone. In some such cases wye-
What are shift registers? Design a 8 bit shift register with features like PISO, SISO, SIPO and PIPO.
What is meant by Daisy Chaining method? It does not need any priority resolving network, rather the priorities of all the devices are effectively assumed to be in sequence.
Define the Gauss Seidel Method The Gauss-Seidel method is an iterative method in which the voltage of each node is calculated in turn using the most up to date voltages for the
The original 8086, which only had 1 MB of memory. This megabyte is dividing into low memory for IRQ tables, application memory and high memory.
An audio amplifier with feedback needs gain of approximately 500 in a 3-dB bandwidth extending from 60 Hz to 25 kHz. Assume this is accomplished using a feedback network with ß=0.0
