A delta connected load consists of three identical impedances Z=45 at 60 degrees per phase. It is connected to a three phase, 208-V source by a three phase feeder with conductor impedance Zfeeder=(1.2+j1.6) Ohms per phase.
A) Calculate the line-to-line voltage at the load terminals.
B) A delta connected capacitor bank with a reactance of 60 Ohms per phase is connected in parallel with the load at its terminals. Find the resulting line-to-line voltage at the load terminals.
Consider a network with a driving-impedance Z. (1) Find expression for P and Q. (2) Find p(t) in terms of P and Q. (3) Suppose that the network is a series RLC. Interpret the result in part (2).

A 12V-DC power supply that gets it's power from the 110V (RMS) wall outlet needs a transformer as a first step in generating its output. The rectification and regulation stage of the power supply needs an input voltage of 15V (peak)
Let us consider the detection of the framing bit in the T1 carrier by the receiver. Assume that the data bits in a frame assume values of 1 and 0 with equal probabilities of 0.5 and independent of each other. The framing bit alternates between 1 a..
