Answer» Solution :Calculatioin of phase difference between curren and VOLTAGE Name of QUANTITY which leads. `X_(L)=omegaL=(1000xx100xx10^(-3))Omega=100Omega` `X_(C)=1/(omegaC)=(1/(1000xx2xx10^(6)))Omega=5000 Omega1` Phase angle `tan varphi=(X_(L)xxX_(C))/R` `tanvarphi=(100-500)/400=-1` `vaphi=-(pi)/4` As `X_(C)gtX_(L)` (phase angle is negative) hence current leads voltage. |
