Hi guys,
I have a question to do for my HND, I've got a good idea of how to do this question but just want to make sure I'm correct. Its this one part that has me stumped.

v=[10 + 50Sinwt + 25Sin(3wt+7.5deg) + 5Sin(5wt-105deg)]
Hz = 50Hz
the circuit has a 10 Ohm resistor and a 1H inductor so
Xl = 314.2

Write the expression for I?

Simple enough if you know how I suppose!! Any help appreciated, thanks.
