v is the sinusoidal voltage source. v= v msin(ωt) Using calculus the current will be represented as i= i msin(ωt + φ) i m  =  v m R2 + ( ωL  -  1 ωC ) 2 X  =   X L   -   X C  =   ωL -   1 ωC φ=tan-1 ( XR )

In series RLC circuit the current may lag or lead the voltage depending on the values of L and C
