Three resistors are connected in delta. If theline voltage is 13.2 kV and the line current is 102.2 A, calculate the following:a. The current in each resistor.b. The voltage across each resistor.c. The power supplied to each resistor.d. The power supplied to the 3-phase load.e. The ohmic value of each resistor.
A rectangular strain gage rosette attached to an aluminumsurface comprises three identical gages (gage factor = 2.1) ofnominal resistance 200 ohms are each connected into a Wheat stonebridge having 3 other resistance values also of 200 ohms.
Electric vehicle supercapacitor. a. A 3000 F capacitor has initial voltage 200 V. If the capacitor is discharged at a constant 60 A, what is the voltage across the capacitor during discharge. b. How long will it take the capacitor to discharge to 5..
Find two renewable energy application where ac/dc converters are used. Explain qualitatively the role of the converter in the application
1) 70 lbs/hr of steam at 300 psia, 500oF passes through a turbine which expands it to a pressure of 30 psia. If the turbine operates with an efficiency of 70%: a) What is the temperature of the steam leaving the turbine
a) both stations begin to transmit at the same time b) one station begins to transmit at the first possible moment such that its transmission would not be detected by the other station before it began its transmission
n other case Trackers have the ability to increase power generated by direct radiation by 40 %. However, the cost of installed system (including trackers) will be $2.60 million. Calculate the cost of generated electricity in the second case.
what are the application of backward diode
A 11 GHz uniform plane wave with maximum electric field of 100 V/m propagates in air in the direction of a x-direction. The magnetic field has only a a(z) component ( in the z direction), which is approximately equal to 100 mA/m at x = y = t = 0.
The nameplate on a 25-MVA, 60-Hz single-phase transformer indicates that it has a voltage rating of 8.0-kV:78-kV. A short-circuit test from the high-voltage side (low-voltage winding short circuited) gives readings of 4.53 kV, 321 A, and 77.5 kW.
A capacitor is made with very large plates separated a distance d. The potential between the plates is V=1000 volts and d = 1mm. a) Calculate the pressure the plates exert on the air between the plates.
Design a 2-bit counter that, when f = 1, counts in the repeating sequence: 0, 2, 3, and when f = 0, counts in the reverse direction. Use T flip-flops. (a) Construct a state diagram or state table.
A 50-KVA, 13,800/208 V ?-Y distribution transformer has an equivalent phase impedance 114.2+j800 ohm referred to the high voltage side. Take the rated voltage as the base voltage and the rated VA as the based voltampere value.
