If Pmax is the maximum power that can be supplied by a cylindrical rotor synchronous machine, state whether the load can be suddenly raised to 0.9 Pmax without destabilising the machine when it is supplying 0.5Pmax . If it is not possible what is the minimum value of the initial load so that increase of load to 0.9 Pmax will not destabilise the machine. Apply equal area criterion neglecting damping andarmature resistance.
A friend of yours claims that the output of any LTI system corresponding to the input x(-t) is y(-t), i.e., time-reversal of input results in time-reversal at the output. Verify this claim,i.e., prove or disprove the assertion.
Design a four-bit counterlike circuit controlled by the input w. If w=1, then the counter adds 2 to its contents, wrapping around if the count reaches 8 or 9. Thus if the present state is 8 or 9, then the next state becomes 0 or 1, respectively.
A circuit consists of a battery connected to three resistors (60ohm , 30ohm , and 180ohm ) in parallel. The total current through the resistors is 1.9A . Find the emf of the battery.
The resistance of a copper wire at 30oCis 50Ω. if the temperature coefficient of copperat 0oC is 0.00427, what is the resistance at100oC
Determine the bending moments and vertical reactions at the supports and sketch the BM and SF diagrams.
One side of the transformer bank is connected to a 120-kV transmission line, and the other side is connected to a three-phase load of 10 MVA at 13.2kV and 0.8 lagging power factor. Using the base in the tranmission line of 120-kV and 20 MVA.
What is the Diversity Factor in Electrical Wiring Installation ??
The system counts the number of events on a single bit input B and always outputs that number unsigned on a 16-bit output C, which is initially0. An event is a change from 0 to 1 or from 1 to 0. Assume the system count rolls over when the maximum ..
The silicon cube you were shown consisted of 4x4x4 unit cells. You were shown one dopant in the silicon cube. Given that the lattice constant of silicon is 0.543 nm. Calculate the dopant density represented by the 4x4x4 silicon cube simulation.
