1. The problem statement, all variables and given/known data

A resistor, inductor, capacitor are connected in series to an AC source. The AC source is operating at the resonance freq. Which are true?
1.The current is in phase with the driving voltage.
2.The peak voltage across the capacitor is greater than the peak voltage across the inductor.
3.The peak voltage across the inductor is greater than the peak voltage across the capacitor.
4.The peak voltage across the resistor is equal to peak voltage across the capacitor.
5.The total voltage across the inductor and the capacitor at any instant is equal to zero.
6.The peak voltage across the resistor is equal to the peak voltage across the inductor.

2. Relevant equations

3. The attempt at a solution

So the current is in phase with the voltage at resonant frequency.
The total voltage across the inductor and capacitor at any instant is zero.

Would that be all? Or am I missing out on some logic...
