Question:

Figure shows a circuit with a resistor, an inductor, and a capacitor in parallel. Kirchhoff?s rules can be used to express the impedance of the system as

Where Z = impedance (?) and ? = the angular frequency. Find the ? that results in an impedance of 75 ? using both bisection and false position with initial guesses of 1 and 1000 for the following parameters: R = 225 ?, C = 0.6 x 10^-6 F, and L = 0.5 H. Determine how many iterations of each technique are necessary to determine the answer to ?_s = 0.1%. Use the graphical approach to explain any difficulties that arise.
