Calculate the value of the thermal voltage, VT at -400C, 00C, +400C and +1500 C. At what temperature is VT exactly 25mV?
A 2.4KV, single-phase circuit suppllies a load of 250KW at a lagging power factor, and the load current is 160A. If it is necessary to improve the power factor, determine the following: (a)The uncorrected poer factor and reactive load.
Design a circuit that will add either 1 or 2 to a 4-bit binary number N. Let the inputs N3, N2, N1, N0 represent N. The input K is a control signal. The circuit should have outputs M3, M2, M1, M0, which represent the 4-bit binary number M.
1-If the AB current in a Y-connected load has an angle of -14°, what is the angle of the a-phase current. (0 decimals in degrees) 2-If the current of the a-phase in a Y-connected load has an angle of -73°
The DC machine rotates at 1500 RPM and it delivers rated current at rated terminal voltage. The field winding is connected to a 120 V supply. Find the value of the field current and the value of R (field control resistance) required.
the doping level of N-type semiconductor is ND = 5x10^19 cm^-3. Determine the room-temperature position of the Fermi level (with respect to the borrom of the conduction band) if the semiconductor is Si (Nc = 2.86x10^19).
Two random variables X and Y have a joint probability density function given by f(x,y) =kxy 0
What will be the total impedance of a series circuit having a resistor of 100 ohms, an inductor of 200 ohms reactance, and a capacitor of 300 ohms reactance. Also, what will be the dissipated power when voltage source is 10sin1000t.
Hand calculate the expression for the voltage and current of the capacitor and plot these equations by using MATLAB and calculate the time constants of each circuit and point out this time constants at your voltage graphs.
Design the simplest circuit that has three inputs x1,x2, x3, which produces an output value of 1whenever EXACTLY one or two of the input variables have the value1; otherwise, the output has to be 0.
