Consider the circuit, consisting of an AC function generator V(t) = V0 sin 2πft with V0 = 5 V, an inductor L = 8 mH, resistor R = 5 Ω and a capacitor C = 100 μF. Which of the following statements are true if we vary the frequency?
1
The current in the circuit would be maximum at f = 178 Hz
2
The capacitive reactance increases with frequency
3
At resonance, the impedance of the circuit is equal to the resistance in the circuit
4
At resonance, the current in the circuit is out of phase with the source voltage
