Can anyone give me a good source where I can get into complex waveforms and LR circuits? As I am asked to obtain a complex current expression from a given complex voltage waveform and a known impedance of series RL circuit.

thanks

From what you describe, it seems you just need to understand the complex impedance and circuit analysis well. Take a look here for starters:

Come back with any questions.
