Three impedances are connected in series across a 100 V, 2 kHz supply. The impedances comprise: (i) an inductance of 0.45 mH and 202 resis- tance, (ii) an inductance of 570 µH and 52 resis- tance and (iii) a capacitor of capacitance 10µF and resistance 30. Assuming no mutual inductive effects between the two inductances, calculate (a) the circuit impedance, (b) the circuit current, (c) the cir- cuit phase angle and (d) the voltage across each impedance.

Question
Three impedances are connected in series
across a 100 V, 2 kHz supply. The impedances
comprise:
(i) an inductance of 0.45 mH and 202 resis-
tance,
(ii) an inductance of 570 µH and 52 resis-
tance and
(iii) a capacitor of capacitance 10µF and
resistance 30.
Assuming no mutual inductive effects between
the two inductances, calculate (a) the circuit
impedance, (b) the circuit current, (c) the cir-
cuit phase angle and (d) the voltage across each
impedance.
