1.	An alternating voltage is applied to a series L-C-R circiut. If the current leads the voltage by `45^(@)`, thenA. `X_(L)=X_(C)-R`B. `X_(L)=X_(C)+R`C. `X_(C)=X_(L)+R`D. `R=X_(L)+X_(C)`
Answer» Correct Answer - B The phase diff. Between I and V is given by `tan theta = (X_L-X_C)/(R)` `:. tan 45^(@) = 1 = (X_L-X_C)/R` `:. X_L-X_C = R or X_L=X_C+R`.
