Hi I'm trying to design a simple amplifier with a voltage gain of 25 for my electronics course for university. I'm at the power supply part and have 12vrms and am using a bridge rectifier with a smoothing cap. I've calculated my Vmax but can't seem to source a formula for the ripple voltage and as such can't work out my Vdc for my amp. The only formula I have is for a bridge rectifier without a cap. can anyone help!
