voltage

Can anyone help me with the powerboard problems. Sonicview 360 premier. All lights are flashing, including logo and channel display. I tested the voltage output and got much higher voltage than specified: 27v at the 22v, 15v at the 7.5 v and 3.39v at the 3.3v. I have changed the 22v, 7.5v...

Hi All! Please help me! Here is my "simple" question: Imagine a condenser, with F and maximum voltage. If I use 3 V, and he has 22 mF, what is the output voltage of this condenser? how do you calculate it? is there a table already with these unswers? Many thanks See you !!
