The equivalent circuit of Figure P3.73 hasVT = 35 V RT = 600Ω If the conditions for maximum power transfer exist,determinea. The value of RL.b. The power developed in RL.c. The efficiency of the circuit
A nonideal voltage source is modeled in FigureP3.72 as an ideal source in series with a resistance thatmodels the internal losses, that is, dissipates the samepower as the internal losses. In the circuit shown inFigure P3.72, with the load resistor removed so thatthe current is zero (i.e., no load), the terminal voltageof the source is measured and is 20 V. Then, withRL = 2.7 kΩ, the terminal voltage is again measuredand is now 18 V. Determine the internal resistance andthe voltage of the ideal source.
The circuit shown in Figure P3.35 is a simplifiedDC version of an AC three-phase electrical distributionsystem.VS1 = VS2 = VS3 = 170 VRW1 = RW2 = RW3 = 0.7Ω R1 = 1.9Ω R2 = 2.3Ω R3 = 11 ΩTo prove how cumbersome and inefficient (althoughsometimes necessary) the method is, determine, usingsuperposition, the current through R1.
