Refer to Figure 1, two impedances Zi and Z2 are connected in series and supplied by a 150V, 50Hz a.c. voltage source. (i) Express impedance Z1 and Z2 in polar form. (ii) Determine the circuit current I in phasor format. (iii) Determine the voltgae VI and V2 in phasor format. ZI R1 = 50; LI = 0.2mH R2 = 30 C = 15 F VI V1 V = 15020 V, 50Hz Fig 1
