A single phase line has an impedance of 8.4 + j11.2 Ω. The line feeds a load consisting of a resistor and an inductor connected in parallel as shown in Figure 1. The load is absorbing 30kVA at 0.6 power factor lagging. The load voltage is 1200Vrms.
Determine:
(a) Values of R and X,
(b) Supply current Ig and the supply voltage Vg,
(c) Total real and reactive power loss in the line.
Q. If the output signal fromanAMmodulator is given by u(t) = 5 cos 1800 πt + 20 cos 2000 πt + 5 cos 2200 πt , determine: (a) The modulating signal m(t) and carrier c(t). (b)
Define Quantization Error? Quantization by its nature introduces errors. There are two major sources of errors. One is sampling, that just takes the amplitude of the signal at
Q. A dc series motor operates at 750 r/min with a line current of 100 A from the 250-V mains. Its armature-circuit resistance is 0.15 and its series-field resistance is 0.1 . As
Series-Parallel Magnetic Circuit: Figure shows an electromagnet made of cast steel contain a coil of 500 turns wound on the central limb. The cross-sectional area of the outer
What is the function of gate signal in 8254 timer? The 8254 has three independent 16-bit counters, which can be programmed to. Work in any one of possible six modes. Every cou
what is working of dc machines?
Q. Dual-ramp analog to digital converter? Figure (a) shows the block diagram of a dual-ramp (dual-slope) A/D converter. After a start-of-conversion pulse, the counter is cleare
Relays a) Sketch the schematic symbol for a relay with a single pole changeover switch b) Determine the coil resistance and determine the current at 12Vdc c) Connect the r
(a) Evaluate whether the sinusoidal signal x(t) = A cos (2πf 0 t + θ) is an energy-type or a power-type signal. (b) Show that any periodic signal is not typically energy type, a
Q. A single-phase, two-winding, 10-kVA, 440:110- V, 60-Hz transformer is to be connected as an autotransformer to supply a load at 550 V from a 440-V supply. Draw a schematic diagr
