- 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.arrow_forwardfind Rt, It, Pt, P1, P2, P3P4,P5,P6arrow_forwardIn the circuit shown in Figure P3.33, F1 and F2 arefuses. Under normal conditions they are modeled as ashort circuit. However, if excess current flows througha fuse, it “blows” and the fuse becomes an open circuit.VS1 = VS2 = 120 VR1 = R2 = 2 Ω R3 = 8Ω R4 = R5 = 250 mΩIf F1 blows, or opens, determine, using KCL and nodeanalysis, the voltages across R1, R2, R3, and F1.arrow_forward
