The frequency response of a low-pass RC filter has a cutoff frequency of:

A 1/(2πL)
B 1/(2πRC)
C RC
D 2πRC

✓ Correct Answer: Option B

Low-pass RC: f_c = 1/(2πRC). Below f_c, signal passes. Above f_c, signal attenuated at -20dB/decade.

💡 Why is B) the correct answer?

The correct answer to the question "The frequency response of a low-pass RC filter has a cutoff frequency of:" is Option B: 1/(2πRC).

The other options — A) 1/(2πL), C) RC, D) 2πRC — are incorrect for this FE Exam Prep question. As explained above: Low-pass RC: f_c = 1/(2πRC). Below f_c, signal passes. Above f_c, signal attenuated at -20dB/decade.
