I'm working and learning about power supplies.
How does one size the voltage of an electrolytic cap after
the diode bridge? At say 24vAC from transformer,
then after diode bridge I read about 21v, but when
the cap is installed, it voltage reads closer to 35v.
Do I need a smoothing capacitor rated for 25v, or 35v?
Maybe a little extra on top?
