Question

PLEASE GIVE FULL BREAK DOWN OF CALCULATIONS, REALLY APPRECIATED

A resistive impedance of 50 2 is connected in series with two impedances of 100 N and 78+ j34 N which are in parallel, as shown in the diagram. 50 Q + R, X, j342 R2 -1002 V R3 78 2 (i) (ii) (iii) Calculate the admittance of the combined parallel branches in polar form. Calculate the input current in polar form when the combined circuit is supplied by 50 20°V. Calculate the output voltage across the parallel branches and the current supplied to the 78+ j34 2 branch in polar form. Calculate the real and reactive powers delivered to the 78+ j34 Q circuit. (iv)
