Q. A three-phase, 600-kVA, 2300:230-V,Y-Y trans-former bank has an iron loss of 4400Wand a full-load copper loss of 7600 W. Find the efficiency of the transformer for 70%full load
Consider the circuit of Figure for t> 0 with zero initial conditions, v Th (t) = 1 V (dc), and R Th = 2 ; L = 1 H. Determine the complete response for vC(t) for capacitance value
A network function is given by (a) For x(t) = δ(t), obtain y(t). (b) For x(t) = u(t), obtain y(t). (c) For x(t) = e -4t , obtain y(t). (d) Express the differenti
Properties of a p-n junction The p-n junction possesses several interesting properties that have helpful applications in modern electronics. A p-doped semiconductor is compara
What makes them sine? Ans) Fourier tells that only a sine wave has no harmonic content. The math works out that if you have any wave shape other than a sign wave, you can brea
Q. Consider a conducting loop of length l and width w, as shown in Figure, rotated about its axis (shown by the broken line) at a speed of ωm rad/s under the influence of a magneti
Q. What do you mean by Conductors and Insulators? In order to put charge in motion so that it becomes an electric current, one must provide a path through which it can flow eas
