An industrial load consumes 88 kW at a power factor of 0.707 lagging from a 480 Vrms line. The transmission line resistance (Rline) from the power company's transformer to the plant is 0.08 Ohms.
Determine the average (real) power that must be supplied by the power company.
The voltage across a 0.2 H coil is given. What is the sinusoidal expression for the current?
Compute the inverse Fourier transform for X(ω) = cos 4ω. 5. A signal with the highest frequency component at 10 kHz is to be sampled. To reconstruct the signal, the sampling must be done at a minimum frequency of?
