Question

In L-C-R circuit the current and voltage are in same phase only at a single freuency. this statement true or false with given reason.

Answer 1

know that in an purely inductive circuit the current lags behind voltage by 90o, in a purely capacitive circuit vice-versa and in an LCR circuit the current may lag or gain with respect to voltage depending on the value of capacitance and inductance. But, does this phase difference exist throughout the circuit

To clarify what I'm asking consider the figure below. Assume the circuit is not in resonance and their is some phase difference. But, does the same phase difference exist between the current and voltage across the resistor Can I find the same phase difference between them if I take any point in the circuit
