An inductive load consists of 1Ω resistance and 1.0mH inductance connected in series. The load is connected across 120V, 60Hz source.
a. Compute the power factor of the load.
b. A capacitor is connected in parallel with the entire load so that no reactive power is delivered by the source. Compute the value of the capacitance.
Compute the energy in BTU and kWh to heat 1000 lb of water from 77°F to 100°F - How much coal will be needed to burn for the same job?
Figure 1 shows the network diagram of a 132kV power system. The network has three buses and two generating units. The loads of (l.O+jO.35) pu and (3.2+J1.2) pu are connected at bus 2 and 3 respectively. The generator connected at bus 2 injects 1.2..
Use MATLAB to compute the inverse Laplace transform of X(s)=(s^2+2s+1)/(s(s+1)(s^2+10s+50)) and determine the value of x(t) in the steady state. How would you be able to obtain this value without computing the inverse? Explain.
