A single phase 4,800<0(degrees) V bus is connected to a singlephase 100-kW motor operating at a lagging power factor of 0.8, alighting load of 200-kW operating at a unity power factor, andstatic capacitors of 150-kvar. Determine the following:a) The total complex power supplied by the bus to the loadsb) The total current supplied to the busc) The power factor of the total load connected to the bus
In a two-winding transformer N1 = 2000 and N2 = 500 and the supply voltage V1 = 1200 V. The transformer has winding resistances R1 = 2.0ohm and R2 = 0.125ohm , and leakage reactances X1 = 8.0 and X2 = 0.5ohm
A VSWR is measured along a transmission line to be 2. Find two values for the reflection coefficient ? Which of these values will correspond to ZL Zc
attend a surplus electronics auction and buy a fancy spot light for the car. when you get home you realized why nobody else bid on the light as it contains a 45-watt, 9 volt bulb and your car ( like most ) has a 12-volt electrical system.
Capture the following system behavior as an HLSM. The system counts the number of events on a single bit input B and always outputs that number unsigned on a 16-bit output C, which is initially0. An event is a change from 0 to 1 or from 1 to 0.
For computer chip of 10mm (length), 10 mm(width) is operated by power of 0.345 watt, which surrounded by coolant material of temp of 70 F. The Internal energy rate is 3.5J/sec and kinetic energy rate is -4.5J/sec.
Develop a Sensor Circuit using commodity components and design a wireless sensor node using commodity wireless modules
the rms voltage of a balanced 3 phase Y connected source is 110 volts at 60Hz. it is connected to a balanced Y Load by 3 distribution lines with an impedence on each line z=1+j2. the load impedence is z=19=j28 per phase.
Two identical 138 kV Y: 13.8 kV DELTA 100 MVA tap changing transformer each with a per unit series impedance of j.1 ohms are operating in parallel and supplying a 180 MVA load at 13.8 kV and .8 lagging pf.
If the earth is considered to be a metal sphere(radius˜6371[km]), how much charge Q must bedeposited on its surface in order for an arc to be established inthe air. If the earth's surface was charged to the value byremoving all the electrons from ..
a). Find the resistance of the aluminum wire 1 m long and 1 mm in diameter. For aluminum, resistivity is 2.8e-6 ohm-cm. b). What is the voltage drop across the wire for a current of 1 A The strength of the electric field inside the wire
why there is no earthing in television, rather it is a very complicated and its plug is always 2 pin. On the other hand mobile charger has got 3 pin plug and therefore earthing is done in it while charging of mobile.
A horizontal conductor that is part of a power line carries acurrent of 7200 A from south tonorth. Earth's magnetic field (60.0 µT) is directed towardthe north and is inclined downward at 70° to the horizontal.
