# RMS Current With Harmonics

An ideal AC voltage source is connected in series with a $$1 \ \Omega$$ resistance and a $$1 \text{ H}$$ inductance. The source voltage (in volts) is given by:

$\large{V(t) = \sqrt{2} \cos(t) + \sqrt{2} \cos(2t)}$

What is the RMS (root-mean-square) value of the current flowing in the circuit (in amps, to 3 decimal places)?

Note: Assume the period of the composite signal to be the fundamental period.
