  17. Fig.23 Circuit for Example 1

  18. Example 1 • a) Use PSpice to find the voltages Va and Vb for the circuit shown in Fig.23

  19. b) Use the PSpice solutions to calculate: • 1)The total power dissipated in the circuit • 2)The power supplied by the independent current source • 3)The power supplied by the current-controlled voltage source

  20. Fig. 24

  21. Fig. 25 output file

  22. 注意事项: • H(电流控制电压源)属性: • 265/13=20.3846(不能用分数表示!)

  23. Q: Why does the PSpice output in Fig.25 give the total power dissipation as 0 W? • A: In PSpice, the total power represents the net power generated by the independent voltage sources in the circuit. If a dependent source or an independent current source is generating power, its value is not included.

  24. Solution a) • From the PSpice output: • Va =104.00V • Vb =106.00V

  25. Solution b) • 1)

  26. 2) P24A(supplied)=104(24)=2496W • 3) PH1(supplied)=106(2)=212W • P(supplied)=2496+212=2708W • Note that the sum of power dissipated equals the sum of power supplied.
