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.
KINEMATICS II 1. The concept of the derivative of the function is exceptionally important. The derivative shows that how fast the function changes when its argument is changed.
