The following three impedances are connected in series across a 40V, 20kHz supply:
(i) a resistance of 8,
(ii) a coil of inductance 130µHand5 resistance, and
(iii) a 10 resistor in series with a 0.25µF capacitor.
Calculate
(a) the circuit current,
(b) the circuit phase angle and
(c) the voltage drop across each impedance.
