Multiple answer 3 points
A 20 Ω resistor, a 10 µF capacitor and a 10 mH inductor are connected in series with a voltage source with an angular frequency, ω, of 1000 radians per second connected across them.
Which of the following facts is INCORRECT.
The magnitude of the effective impedance of the circuit, $Z_{eff}$, in polar form is 92.2 Ω
The impedance angle is -77.47 degrees
The current waveform lags the voltage waveform
The overall impedance is capacitive in nature
There is not enough information given in the question to determine the magnitude of the current
