Hi Everyone,

How to calculate the cut of frequency of Parallel RC circuit is shown below?. Anyone could you provide the formula for this?.

Hi

You have straight lines (without an electronic device in series) from input to output. Thus all the input voltage is the same as output voltage.
--> it is no filter at all. It has no cut off frequency.

--> do R and C in series.

The schematic looks like from a simulation tool. If so: Use this simulation tool to simulate your circuit.

RC filters are very basic electronic topics. Thus there are many (millions) of documents, descriptions, examples, even videos in the internet. Please use this information.

A forum can't replace school or internet search.

Hi,

I took this also into account.
But it clearly states "Vin" and "Vout".

I wonder why the voltage vectors are in opposite direction (than I expected) .. but functionally it makes no difference.
