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 Share with your friends Share 1 Vara answered this 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 2 View Full Answer
