The load of an industrial plant is 400 kVA at a power factor of 75 percent lagging. An additional motor load of 100 kW is needed. Find the new kilovoltampere load and power factor of the plant load if the motor to be added is (a) an induction motor with a power factor of 90 percent lagging, and (b) an 80 percent leading power factor synchronous motor.
Find the total current I and the voltage across the capacitance. R = 420 ohms. capacitance = 292 ohms. inductance = 250 ohms. Source voltage 100 angle 0 degrees, 60 Hz.
a) Draw the state diagram b) Draw the schematic for the logic to implement this circuit using Inverters, AND gates, OR gates and D flip flops. Use the reverse side and additional sheets if needed.
Design a circuit that will multiply the input voltage by +12. That is the output voltage is 12v1 where v1 is the input voltage. All resistors should be at least 12ohms.
Semiconductor A is direct band gap and semiconductor B is indirect gap. For providing same short circuit current density of a solar cell, which material will need more thickness
The bottom of the conduction band at one end of a silicon resistor is at the same energy level as the top of the valence band at the other end. What current flows through the resistor if the resistance is 1.12 kOhms
A first order highpass filter is required to satisfy the following specifaction fs=10000Hz fc=4000Hz Find the transfer function and difference equation by the pole-zero placement method.
A) the current decreases by a factor of 1000 in .2s B) the time required for the current drop to half of its intial value is .1s less than the time required for it to drop one-quarter of its intial value.
An initially charged capacitance discharges through a resistance. At one time constant, what percentage of the initial voltage reamins What percentage of the initial stored energy remains
A 10m diameter cylindrical tank is emptied by a constant outflow of 1 m3 /min. A two position controller is used to open and close a fill valve with an open flow of 3 m3 /min. For level control the neutral zone is 1m and the setpoint is 10m.
With regard to assembly language and the HCS12: What is the instruction to initialize the SP register Why do we initialize that register What is the reason we initialize it with the value $4000 for this microcontroller
The frequency response of an FIR filter is H(ejw)=b0+b1*e^-jw+b2*e^-2jw. In each case below, state whether the filter is highpass, lowpass, bandpass or band stop and draw the pole zero plot.
