helo all,

I am making a voltage divider circuit (from 230V rms to 395V rms),in this i want to use a capacitor as a filter,how to decide the value of the capacitor i.e what appropriate value of capacitance and voltage to be taken for capacitor??any1 please focus some light in this?

 

Read the tos first.
Meddling with mains is dangerous and not allowed to be discussed in AAC as I recall.

 

What Rifaa said.

Transformerless power supplies are a restricted topic, as can be seen in the Terms of Service (http://www.allaboutcircuits.com/l_tos.html), Chapter 6.

I'm sorry, but we can't help you there.
