Q. Explain Power-System Loads?
Figure represents a one-line (single-line) diagram of a part of a typical three-phase power system. Notice the symbols that are used for generators, transformers, buses, lines, and loads.
Let us now consider the addition of a load bus to the operating power system. Service classifications assigned by the electric utilities include residential, commercial, light industrial, and heavy industrial loads, as well as municipal electric company loads. Let us prepare a load- bus specification, which is a summary of the service requirements that must be provided by the electric utility. Referring to the simple model of Figure, as an example, let the total new load connected to the system be 220 MVA at 0.8 power factor lagging; let the service be provided at the subtransmission level from a radial 115-kV circuit; let the 115-kV transmission line have a per-phase series impedance of 3 + j8.
Q. (a) Determine the Thévenin and Norton equivalent circuits as viewed by the load resistance R in the network of Figure. (b) Find the value of R if the power dissipated by R is
Process The rectangle symbol is used to represent the process operations as shown below. MOV A, B
having looked at the circuit, i first wanted to start my frequency from 0 and plot for 10000 to 20000. so in matlab i used f = 0:10000:20000; but the equation for frequency is f= 1
Why memory decoding is required? To attach a memory device to the microprocessor, this is necessary to decode the address sent by the microprocessor. Decoding creates the memo

If a high resolution emcoder is used for position control, will the number of pole count in the DC motor be matter? What is the requirement for the DC motor in order to work with h
Q. Illustrate Breakpoint Analysis? When a circuit consists of two or more ideal diodes, it will have several distinct operating conditions resulting from the off and on states
Q. Consider the circuit shown in Figure. (a) Given v(t) = 10e -t V, find the current source is(t) needed. (b) Given i(t) = 10e -t A, find the voltage source v (t) needed.
