1. can a transformer ratio LTC control MW or Mvar power flow on a parallel transformers? why?2. what test is used to calculate a transformer through fault impedance?3. List three design or operating factors which make a generator more stable?
A battery is charged. The relationship between the charging current, i amperes and the time, t hours passed, is given by the formula:
Complete the design, including a schematic, of the implementation of the second version of the Gumball Vending Machine Example using D Flip Flops AND JK Flip Flops. Which of the two is the better design
Calculate the L and C values of an L network that is to match a 9 ohm transistor power amplifier to a 75 ohm antenna at 122 MHZ.
Build a home security system circuit using this program. The system must include a door sensor,window sensor, smoke detector, water leak sensor, a motion detector.
Design and test a 4-bit ripple carry adder, i. e., an array of 4 full adders, that adds any 4-bit binary number A3A2A1A0 to the 8-4-2-1 BCD code of the third and fourth non-zero and different digits of your Red ID number.
The voltage across the load must remain between 4.7 and 5.0 V for all values of load current. Come up with (draw) a voltage-divider network to supply the load. You may assume that resistors of any value desired are available.
A 150kVA, 2080/208V, 60Hz, Y/Y connected, three-phase, step-down transformer consists of three identical single-phase transformers. Each transformer has the following parameter values: Rl = 0.45-ohm, Xl = 2.2-ohm , R2 = 4.5m-ohm
Write a balance reaction equation for the complete combution of carbon in air. What are the mass and mole fraction of fuel, air oxygen and notrogen in the reactants
Three loads are connected in parallel across a single-phase source voltage of 240 V (RMS). Load 1 absorbs 12 kW and 6.667 kVAR; Load 2 absorbs 4 kVA at 0.96PF leading; Load 3 absorbs 15 kW at unity power factor.
A 75-kVA, 230-V/115-V, 60-Hz was tested with these results: Open-circuit test: 115 V, 16.3 A, 750 W; Short-circuit test: 9.5 V, 326 A, 1200 W a) Determine the voltage regulation at rated load, 0.8 power factor lagging.
Draw the equivalent circuit referred to the high-voltage side.
The voltage across a resistor is given by Ohm's Law: V=R I. Write a program that asks for resistance R in ohms, and current I in amps for several resistors, then calculates and displays the voltage across each resistor.
