Question 2 (7 marks) Consider an electric circuit with a resistor of resistance R, an inductor with inductance L and a capacitor with capacitance C. The impedance Z of the circuit is given by z - (+2012.- ame) . R2 2nL 1 2πηC where n is a frequency. (a) Rearrange this equation to make the subject. Show all your steps. (3 marks) (b) Show that if n = 50, C = 10-4 and R= 15, there are two values for L such that Z = 20, but only one solution for L such that Z 100. (4 marks)
