An lcr series circuit has R =100 ohms ,L=0.5 H, ,c= 100Am^2F . The alternating emf of peak value 240 volts and frequency 50 Hz is applied to it .find impedance of the circuit and max current in the circuit

Inductive reactance:XL=2πfL     =2π×50×0.5     =157.1 ΩCapacitive reactance:Xc=12πfC    =12π×50×100    =3.18×10-5 Ω(a)Impedance:Z=XL2+XC2   =157.12+3.18×10-52   =157.1 Ω(b)Maximum current:I=VZ  =240157.1  =1.53 A
