Hi all : )

Im designing a 15 V DC regulated supply.

Im calculating filter capacitor value for it using following formula,

C= (0.7*I)/(100*Vr)

where, I is load current

Vr is ripple voltage

0.7 because capacitor supplies the current for 70% of cycle

**i want to know how much ripple voltage should i take for my calculation ??**
