6. Using the branch where -π < θ < π for the function f(z) = √z, with z = r e^(iθ), show that the residue of the function: f(z) = (√z) / (1 - z) at z = 1 is -1. If we choose the branch (2n-1)π < θ < (2n+1)π, where n is an integer, what is the value of the residue at z = 1? Justify.

Q4 20 marks]: Consider the thyristor circuit shown in Fig. 1(a), plot the voltage across and the current through the resistance B according to the input v, shown in Fig.1(b). Assume the thyristor's break down and breakover voltages are 200V and its maximum current is 50A. Also, let R=10Omega and the peak values of v_(s)=+-400V, show all your work and calculations.
