A series circuit consists of a resistance inductance and capacitance.The applied voltage and the current at any instant are given by `E=141.4 cos(5000

Correct Answer - `4 muF,R=141.4/5 Omega` Here phase difference `(0)=360^(0)` & `omega=5000` at Resonance `C=1/(5000)^(2)xx1/(0.01)` `R=V_(0)/I_(0)=141.4/5`
