A voltage e=250sinωt+50sin(3ωt+pi/3)+20 sin(5ωt+(5pi/6)) is applied to a series Circuit of resistance 20Ω and an inductance of 0.05H. Take ω=314rad/s
3.1 Derive an expression for the current.
Calculate the following:
3.2 The rms value of the current and voltage.
3.3 The total power supplied.
3.4 The power factor.
Thanks for the answer, I fully understand
