The following test data were taken on a 110-KVA, 4400/440- volt, 60-Hz transformer:
Short Circuit Test: P= 2000w, I = 200 amp, V = 18vOpen Circuit Test: P=1200w, I= 2 amp, V = 4400v
Calculate the voltage regulation of this transformer when it supplies rated current at .8 pf lagging. Neglect the magnetizing current.
how the amplifiers should be connected. To proceed, evaluate the two possible connections between source S and load L, namely, SABL and SBAL. Find the voltage gain for each both as a ratio and in decibels. Which amplifier arrangement is best
Assume that the load is star connected with the neutral disconnected. Each phase has a series RL load with R = 5 ohms and L = 20 mH. Plot the neutral voltage Plot the phase to neutral voltage for phase a.
Each pole of a 100kW, 250v flet-compound generator has a shunt field of 2000 turns and a series field of 7 turns. If the total shunt field resistance is 100 ohms, calculate mmf when the machine operates at rated voltage.
What, exactly, is necessary to establish electrical continuity between two wires. If want to have an electric current flow out of one wire and into another, what must be done with those two wires to make that flow path complete.
A single phase 220V system draws a current of 15A at a lagging power factor of 0.8. Calculate the value of a capacitor that can be used to improve the power factor of this system to 0.95 lagging.
The amount of three phase power to be delivered in ‘kW' is equal to the total number of letters in your name (first name +last name) and the single phase power is 10% of three phase power. Assume same power factor for both types of loads.
Using MatLab, create and graph the pairwise convolution of the following functions (i.e., A must be convolved with B, C, D, and E, individually. B must be convolved with C, D, and E, individually, Etc.). All time scales are -4 to +4.
Write an equation to help determine P-type body doping concentration Na for a required threshold voltage V (sub TN) for an N-channel Al-Sio(sub 2) -Si MOSFET. Use the equation to design an N-MOSFET with a thershold voltage of 10V
A 60-Hz, single-phase transmission line has a length of 80 miles. Its shunt conductance (G) is 3.4×10?11 S/mile, resistance (R) is 0.1 ?/mile, capacitance (C) is 16 pF/mile, and inductance (L) is 0.56 mH/mile.
Consider a digital filter with frequency response: H(f)=11+f Assuming the sampling frequency is 1500Hz what is the frequency attenuation of a signal passing through this filter at 280Hz
Write a program to determine how many from your data set called MYDATA, which is a set of unsigned single-byte numbers, are odd numbers. Save the result in TOTODD at address 0x10 in the data memory.
