The following data were obtained or a 30-kva, 60 hz, 2400-240V transformer tested at 60hz.
Voltage (V), Current(A), Power(W)
O.C. Test 240V, 3.0 A, 230 W
S.C. Test 70V, 18.8 A, 1050 W
a). determine the primary voltage when 12.5 A at 240 V is taken from the low voltage side supplying a load of 0.8 p.f. lagging.
b). Compute the efficiency and regulation in part (a)
Two random variables X and Y have a joint probability density function given by f(x,y) =kxy 0
An uncharged capacitor and resistor are connected in series with a 12V source and switch. What is the voltage across the capacitor after the switch is closed and the capacitor is fully charged
A 600V, dc shunt motor has an armature and field resistance of 1.5 ohm and 600 ohm, respectively. When the motor runs unloaded, the line current is 3A, and the speed is 1000 rpm.
Calculate the parameters RE and XE, and the maximum efficiency and power output for the transformer when a load with a 90% lagging power factor is connected to the transformer secondary winding.
he operation of the system requires that, before any change of motion direction, the motor must be in a full stop by push the "STOP" button Assuming bother timer TD1 and TD2 have the same preset time of 1 minute
Using the Nth order term only of the transfer polynomial, find the Nth order relationship for the Nth order products.
Suppose that a family of logic gates considers the output ranges of [0 - 0.2V] as "0" and [3.1V-3.3V] as "1". What are the reasonable input ranges for "0" and "1"? (a) "0": [0.1 - 0.4V], "1": [2.3V - 3.3V]; (b) "0": [0-0.3V], "1": [2.8V - 3.0V]; (..
A container with a plunger compresses one pound mole of an ideal gas from 1 atmospheres pressure to 10 atmospheres. Calculate the amount of work done if the process is considered to be polytropic.
A) If 220kV, 220 MVA with power factor 0.8 lagging is determined to be at the receiving end, calculate the voltage at the transmitting end. B) If 220kV, 220 MVA with power factor 0.8 lagging is determined to be at the receiving end
An underdamped sensor with a static sensitivity of K=1, undamped natural frequency of omega=1400 rad/s, and damping ratio of zeta=0.5 is used to measure a sinusoidal signal with a frequency of 6 kHz.
Write a program that uses the rand_float functions developed to generating sequences of random floating-point values between 4 and 10. Then compare the computed mean and variance to the theoretical values computed.
(a) Design a simple PNP current source to give an output current of IO = 0.5 mA (nominal value). The transistor parameters are f = 50, VEE = 10 V, VCC = 10V, |VBE| = 0.7 V, |VCEsat| = 0.3 V and VA = 50 V (for all transistors)
