A factory load of 900 kW at 0.6 power factor lagging is to be increased by the addition of a synchronous motor that takes 450 kW. At what power factor must this motor operate, and what must be its KVA input if the overall power factor is to be 0.9 lagging?
clearly explain the computational advantages of applying lu factorisation when forming and storing the admittance
A three-phase overhead transmission line has a per-phase resistance of 0.15 ohm/km, and a per-phase inductance of 1.3263 mH/km.
Calculate the total electrical energy that can be generated from the power station.- If a load of 15,000 kW has been supplied for 3 hours, find the fall in reservoir level.
Obtain the expression for the time constant of the system. Find the value of a. Find the value of the constant K.
A "Clock" pulse for a flip-flop could be generated by manually filpping a switch from 0 to 1 and then back to 0. but switches such as those on the logic designer "bounce" when switched from on state to another.
Two resistors of resistance R_1 and R_2, with R_2>R_1, are connected to a voltage source with voltage V_0. When the resistors are connected in series, the current is I_s. When the resistors are connected in parallel, the current I_p from the sourc..
The charge entering the positive terminal of an element is q(t) =-30e-4t mC. If the voltage across the element is120e-2t V, determine the energy delivered to the elementin the time interval 0
An electron is confined inside a potential well with infinite walls. The width of the of the wells = 5nm. What is the probability of finding a electron within 1nm from either wall if the electron is at: A)the lowest energy level B). the 2nd lowest ..
An InP TED is 0.5 pm long with a cross sectional area of 10" cm2 and is operated in the transit-time mode.(a) Find the minimum electron density no required for transit-time mode.
It involves developing a function called "single_phase_transformer_tests" that can work on user input data to generate the transformer voltage regulation and efficiency under various loading criteria.
At what speed does the fan rotate?
Design a circuit that implements the logic function "f = A' + B" using only two single pole/single throw switches, an LED, and a current limiting resistor.
