Please help with this question, I am a little confused with the peak-to-peak ripple as I cannot find the appropriate formulas to apply to this circuit.

All work and steps included please!

4) 5-34 - In Fig. 5-41, the secondary voltage is 12.6 V rms, and diode drops are 0.7 V each. The 1N5314 is a constant-current diode with a current of 4.7 mA. The LED current is 15.6 mA, and the zener current is 21.7 mA. The filter capacitor has a tolerance of +/ 20 percent. What is the maximum peak-to-peak ripple? Leo- A V130LA2 115 V ac R1 R2 1N5314 1000 F
