Q. A balanced three-phase, wye-connected, 2400- V, 60-Hz source supplies two balanced wye- connected loads in parallel. The first draws 15 kVA at 0.8 power factor lagging, and the second needs 20 kW at 0.9 power factor leading. Compute the following:
(a) Current supplied by the source.
(b) Total real and reactive power drawn by the combined load.
(c) Overall power factor.
Consider the analog averager where x(t) is the input and y(t) is the output. (a) Find the impulse response h(t) of the average. Is this system causal? (b) Let x(t)
