Hi everyone..
Good morning/evening..
I hope you all fine..
I have a project and I need your help..

I have this RC CIRCUIT

Assume the following:


I need to find V(out) (magnitude only), in the Phasor domain, in terms of the frequency ω and I need to show that the cutoff frequency of this circuit is 1/RC.

Can any body help me with that..? I will be Grateful.

Is this project school related?

Generally cutoff is when the reactance of the capacitor equals that of the resistor (or inductor).
