### Techniques of Circuit Analysis #### Section 4.8 **Problem 4.54** Assume you have been asked to find the power dissipated in the horizontal 1 kΩ resistor in the circuit in Fig. P4.54. - **(a)** Which method of circuit analysis would you recommend? Explain why. - **(b)** Use your recommended method of analysis to find the power dissipated in the horizontal 1 kΩ resistor. - **(c)** Would you change your recommendation if the problem had been to find the power developed by the 10 mA current source? Explain. - **(d)** Find the power delivered to the 10 mA current source. **Figure P4.54**: A circuit diagram showing a 10 mA current source connected to a network of resistors. **Problem 4.55** A 4 kΩ resistor is placed in parallel with the 10 mA current source in the circuit in Fig. P4.54. Assume you have been asked to calculate the power developed by the current source. - **(a)** Which method of circuit analysis would you recommend? Explain why. - **(b)** Find the power developed by the current source. **Problem 4.56** Would you use the node-voltage or mesh-current method to find the power absorbed by the 200 mA source in the circuit in Fig. P4.56? Explain why. - **(a)** Choose the method you selected in (a) to find the power. **Figure P4.56**: A circuit diagram illustrating a network containing a 200 mA current source. **Problem 4.57** The variable dc current source in the circuit in Fig. P4.57 is adjusted so that \(i_0\) is zero. - **(a)** Would you use the node-voltage or mesh-current method to find \(i_0\)? Explain your choice. - **(b)** Use the method selected in (a) to find \(i_0\). **Figure P4.57**: A circuit diagram including a variable current source adjusted for specific conditions. **Problem 4.58** The variable dc voltage source in the circuit in Fig. P4.58 is adjusted so that \(i_a\) is zero. - **(a)** Would you use the node-voltage or mesh-current method to find \(V_a\)?
