Find the valuee of V5 pls help

5) please solve with work! will upvote!

for the given circuit find p & q for the load as shown

Ge 10:1 m Thanks Any help will be appreciated. S BL • I am doing a AC DC 12 W Regulated power supply with 110 vrms and 60HZ as an input, and I need an output of 6v and 9 V. I have the designed already: the step-down transformer, Resistor as a current limiter to protect the Zener diode, a capacitor for the ripple voltage, and a 2 state switch ( when the switch is closed to the RL will give 9 V and when is closed to the S will give 6V as an output). • I need some support with some calculations to find PIV for each diode // Average Power// some calculations in how to find the values for the resistors and capacitors to accomplish the desire output // and some calculations for the ripple voltage. Note: the Zener is regulated to 9v. I know the RL>R to get the desire output.
