The following impedances are connected in parallel in the electric circuit. Z1 = 4 + 9j Z2 = 4 – 1 Z3 = 2 – 9j If the equivalent impedance of the circuit is given by Z where 1 1 1 + + Z1' Z2' Z3 = - i. Find the equivalent impedance and express it in polar form. ii. Find the current I flowing in the circuit when a 230 V AC voltage source is connected to it, where the current is given by. V I =- iii. Deduce the square apparent power P, = 1*z² of the circuit using de Moivre's theorem where necessary. iv. Due to a malfunction in the power supply, it was found that the square apparent power P, of the circuit dropped by half. Assuming that the impedance Z remained constant, calculate the current I flowing in the circuit during the malfunction using the equation given in part ii. Use de Moivre's theorem in your calculations where necessary.
