Question

Why we are laplace transform in finding the transient response for any D.C circuit

Answer 1

I don't think we use laplace tranform to plot transient response for DC circuit , because transient response is viewed in respect to time, not frequency

Answer 2

for dc only i am saying , i have seen in my text book. they have solved the diffrential equation using laplace and classical method for finding the transient current

Answer 3

Friend, wherever there are differential equations involved, even if it is transient response of dc circuit, we can use Laplace Transform.
In a circuit with energy storage elements, voltages and currents are the solutions to linear, constant coefficient differential equations, therefore we can use Laplace Transform in dc transient response analysis also.

Answer 4

finding transient response is just solving a differential equation ,by laplace trasform we do it easily with out bothering about the intial conditions unlike solving differential equations in convential way
