Question:
A 3phase transmission line 200 km long has the following constants
•Resistance / phase / km=0.16 ohms•Reactance/phase/km= 0.25 ohms•Shunt admittance/ phase/ km =1.5 *10-6 S
Calculate by rigorous method the sending end voltage and current when the line is delivering a load of 20 MW at 0.8 p.f. lagging. The receiving end voltage is kept constant at 110 kV.
The voltage and current at the terminals of the circuit element ate zero for t 40 s. In the interval between 0 and 40 s the expressions are. At what instant of time is the power being extracted from the circuit element maximum.
How to decide the shortest possible clock period for a synchronous circuit with the flop-based clocking. What is the hold time of a register. How does the hold time constrain the circuit delays for a synchronous circuit.
A BJT is being used as a switch and is triggered whenever thebase-emitter voltage v(t) rises above 0.15 volts. The voltage v(t)is sinusoidal and changes according to v(t )= 0.23cos( 100π t)+ 0.16sin(100π t + 0.4) . a) Express v(t) a sine function ..
What is the ratio of cost to performance for each option, compared to the original system?
(a) Determine a unit vector in the direction of Q at P(1, 2, 1) (b) Find the component of Q at P in the direction of PT where T is point (5, 3, -4) (c) Where is Q the same as the unit vector of \(a_{x}+11a_{y}+10a_{z}\)
A box contains a shipment of N (N>4) computer chips, of which four are defective. Four chips are randomly selected and examined as to wether or not the chips are defective. Describe the sample space for this experiment.
A certain type of D-cell battery that costs $0.50 is capable of producing 1.2 V and a current of 0.1 A for a period of 75 hours. Determine the cost of the energy delivered by this battery per kilowatt hour.
A student attempts to measure his own ECG on an oscilloscope having a differential input. For Figure 6.11, Zin ¼ 1MV, Z1 ¼ 20 kV, Z2 ¼ 10 kV, ZG ¼ 30 kV, and idb ¼ 0:5mA. Calculate the power-line interference the student observes.
The system receives three binary streams: A, B, and C. The system takes a look during each clock cycle at the last four bits of each stream (a(t), a(t-1), a(t-2), a(t-3)), (b(t), b(t-1), b(t-2), b(t-3)) and (c(t), c(t-1), c(t-2), c(t-3)).
When the motor runs at 1710 rpm, the line currentdrawn from the supply is 78 A at 0.85 PF lagging. Given that,stator iron loss is 2kW, windage and friction losses are 1.2kW andresistance between two stator terminals = 0.4W
Given the ratings of a single-phase transformer - 3kVA 220V/110V 50 Hz, calculate the rated current for the primary winding and the rated current for the secondary winding. The currents in the transformer should not exceed these values during the ..
