A coil having an impedance of (10 + j100) Ω is connected in parallel to a variable capacitor as

Q. A coil having an impedance of (10 + j100) Ω is connected in parallel to a variable capacitor as shown in figure. Keeping the excitation frequency unchanged, the value of the capacitor is changed so that parallel resonance occurs. The impedance across terminals p-q at resonance (in Ω) is  

Ans: 1009 – 1011
