Two industrial plants represent balanced three-phase loads. The plants receive their power from a balanced three-phase source witha line voltage of 4.6kV rms. Plant 1 is rated at 300kVa, .8 PFlagging, and plant 2 is rated at 350kVa, .84 lagging. D..
If an alternating voltage, v, given by v = 200 sin 500t volts is applied across the coil, calculate (a) the circuit impedance, (b) the current flowing, (c) the p.d. across the resistance, (d) the p.d. across the inductance and (e) the phase angle ..
Three delta connected transformers are supplying a balanced reactive load. The primary line voltage is 480 volts and the primary line current is 20.5 amps. The load power used is 4.8kw. What is the power factor, the apparent power supplied
A signal with Fourier transform F(jw) = 20/(4+jw) is passed through an ideal low pass filter whose cutoff frequency is 2 rad/sec (i.e., 0
Design a circuit to give uninterrupted 5 V dc power supply with 110 V 60 Hz line voltage as input. The dc output should be available in case of power outage (110 V line supply). In case of line failure, the circuit should switch to backup source t..
QI The circuit diagram of an active linear filter is shown in Figure Ql. (a) Derive an expression for the transfer filmiest of the filter. (b) Hence find an expression for the frequency response of the filter.
A capacity coupled amplifier has a midband gain of 1000 V/V, a single high-frequency pole at 10 kHz, and a single low-frequency pole at 100 Hz. Negative feedback is employed so that the midband gain is reduced to 10.
an office with several work stations has an effective area of 527 sqft (49 meters). it has decorative incandescent lighting. The lamps are 40 watt yielding an out put of 18 lm/W. An illumination of 645 lux is required for the work stations.
a 10 hp, 230v , 1200 rpm dc series motor draws a current of 36 A when its under rated voltage at its rated speed Ra = 0.2 Rf = 0.1 a) find the speed of this motor when its taking a current of 24 A. b) determine the developed torque if this motor for..
How will the reading of two ammeters compare if they are placed in series in a circuit Will the answer to this question be different if the resistance of the two ammeters is not the same
Using nodal analysis solve for the current and supemode used to solve this circuit is located between which two nodes?
