You have a series circuit consisting of a ac power supply, a 1150.0 ohm resistor and a 144.0 nF capacitor. If the circuit is configured as a low pass filter, what frequency will cause the gain to be 0.25?
Formula
Gain = Vout / Vin = R / [R^2 + (1/ωC)^2]^1/2Solution
Plugging in R=1150 ohms
C=144*10^-9 F
to find a value for ω
And then using ω=2 π f
I got f= 0.05223Hz which is wrong.
Also what will be the formula for high pass filter?
Please help!
