At very low frequencies a series R-C circuit behaves as almost purely___________?
Correct answer: C. capacitive
- A. resistive
- B. inductive
- C. capacitive
- D. none of the above
Explanation
At very low frequency, capacitive reactance Xc = 1/(2πfC) becomes very large, so a series R-C circuit is dominated by its capacitive impedance.
