The impedance of an RC series circuit is 12 Ω at f= 50 Hz. At f= 200 Hz, the impedance will be

1.

The impedance of an RC series circuit is 12 Ω at f= 50 Hz. At f= 200 Hz, the impedance will be

[A].	more than 12
[B].	less than 3
[C].	more than 3 Ω but less than 12 Ω
[D].	more than 12 Ω but less than 24 Ω

Answer: Option C

Explanation:

Z = √R2 + XC2. When f is made four times, XC becomes one-fourth but R remains the same.
