Q. Athree-phase, 60-Hz transmission line has a total series impedance of 22.86 62.3° per phase. It delivers 2.5 MW at 13.8 kV to a load connected to its receiving end. Compute the sending-end voltage, current, real power, and reactive power for the following conditions:
(a) 0.8 power factor lagging.
(b) Unity power factor.
(c) 0.9 power factor leading.
Explain Diffusion. Diffusion : Though, the mobility of the carriers in a semiconductor is greater than the electrons in metals, the conductivity in the former is much less t
Q For a parallel-plate capacitor with plates of area A m 2 and separation d m in air, the capacitance in farads may be computed from the approximate relation Compute the a
Q. A rotating electric machine with uniform air gap has a cylindrical rotor winding with inductance L 2 =1 H and a stator winding with inductance L 1 =3H. Themutual inductance va
Q. Use MATLAB to obtain the Laplace transform of the waveform f(t) = [200t e -25t + 10 e -50t sin(25t)]u(t) which consists of a damped ramp and a damped sine. Also show the
Since dc motors of various types are used extensively in control systems, it is essential for analytical purposes that we establish a mathematical model for the dc motor. Let us co
