QUESTION 3 [25 marks] (a) Let R =10.00, X, =5.0002 and X = 20.00. (i) Calculate the magnitude and phase angle of the impedance using Z = R+ (X, - X) j. (ii) Calculate the magnitude of the voltage across the combination at the instant when / =4.214 using V|= /|Z|. (b) Compute the absolute value and argument of -2j(3+ j)(2+4/)(1+ j). (c) Two impedances, Z, =(1+2/)02 and Z, =(1-2j)0 are connected in parallel. The total impedance, Z, is given by Zy =- 2142 Determine the total impedance of a circuit, Z,. Z , + Zz
