Current of 50/pi Hz frequency is passing through an A.C. circuit having series combination of resistance R = 100Omega and L = 1 H, then phase difference between voltage and current is ………. |

Answer» Solution :`f=50/pi` Hz `THEREFORE omega=2pif =2pixx50/pi`=100 rad/s `X_L=omegaL=100xx1=100Omega` and in R-L series A.C. circuit, the phase difference between voltage and current `delta=TAN^(-1)(X_L/R)=tan^(-1) (100/100)=tan^(-1) (1)` `therefore delta=pi/4` or `45^@` |
