Q1: 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

ANS:C - more than 3 Ω but less than 12 Ω

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