Hi everyone!
I hope you people can help me out at a problem I am stuck with:
Find the peak voltage across the capacitor "C"
All variables given and an image of the circuit are:
2. The attempt at a solution
To be honest - I don't even know where to start this problem. The only thing which I thought to do is to calculate the peak voltage of the battery. Which is 35.36V. The next step I thought to do is to calculate the voltage across the bulbs - however I don't have any current value.
Any breadcrumbs to get me started would be great.

Homework Statement
Find the peak voltage across the capacitor "C"
All variables given and an image of the circuit are:

- The circuit is connected to an AC battery of 25V labeled as "U" in the diagram.
- Lightbulbs "L1" and "L2" use 5.5 W each
- Lightbulbs "L3" and "L4" use 2 W each
- All bulbs will light up if they each receive 4.5V (thats exactly how the question states it)
- Resistance across point "A" and "B" is 5.4 Ohm
