In the figure shows R=100Omega, L=2/(pi)H and C=8/(pi) muF are connected in series with an a.c. source of 200 volt and frequency f. V_(1) and V_(2) are two hot-wire voltmeters. If the reading of V_(1) and V_(2) are same, then |

Answer» `f=125Hz` `impliesf=1/(2pisqrt(LC))=125Hz` `I_(0)=(v_(0))/R=200/100 ( :' x=0, :.z=R)` `V_(1)=V_(2)=IX_(L)=I.(OMEGAL)=IL . 1/(sqrt(LC))=Isqrt(L/C)=2sqrt(((2//pi))/((8xx10^(-6)//pi)))=1000` volt |
