The complete solution of the current in the sinusoidal response of R-L-C circuit is?
(a) i = c1 e^(K1+K2)t + c1 e^(K1-K2)t – V/√(R^2+(1/ωC-ωL)^2) cos(ωt+θ+tan^-1)((1/ωC-ωL)/R))
(b) i = c1 e^(K1+K2)t + c1 e^(K1-K2)t – V/√(R^2+(1/ωC-ωL)^2) cos(ωt+θ-tan^-1)((1/ωC-ωL)/R))
(c) i = c1 e^(K1+K2)t + c1 e^(K1-K2)t + V/√(R^2+(1/ωC-ωL)^2) cos(ωt+θ+tan^-1)((1/ωC-ωL)/R))
(d) i = c1 e^(K1+K2)t + c1 e^(K1-K2)t + V/√(R^2+(1/ωC-ωL)^2) cos(ωt+θ-tan^-1)((1/ωC-ωL)/R))
The question was asked in final exam.
My question comes from Sinusoidal Response of an R-L-C Circuit topic in division Transients of Network Theory
