✔ 最佳答案
phase difference between the p.d. and the current : π/2 ( theoretical value) /less than π/2 ( exptal value if R is large)If R is larger than before, phrase difference is less than π/2
this is because current is compared with p.d. across L and R, rather than that across L.
the same apply to RC and LR circuit.
