Please do parts b-d. 2. Consider the circuit shown below. 0.2i 7 2 4Ω 1Ω 4Ω 0.1 va (a) By hand, use any method (node voltage, mesh currents, etc.) tosolve for the currentix b) Using Spice, solve for...
2. Consider the circuit shown below. 0.2i 7 2 4Ω 1Ω 4Ω 0.1 va (a) By hand, use any method (node voltage, mesh currents, etc.) tosolve for the currentix b) Using Spice, solve for ix and compare with your hand calculation. (c) Plot Va vs. Vs, where Vs replaces the 9 V voltage source (and has the same polarity) and varies from -20 to 20 volts. At what value of Vs does the direction of the current ix charge? (d) For Vs-9 V, are the two dependent sources absorbing or supplying power?
