In steady state a system behaves normally everything is fine with the circuit but if any fault occurs or any inp. Transient analysis always begins at time=0, and assumes that only the DC sources were connected to the circuit prior to that time. sinusoidal input. In electrical engineering specifically, the transient response is the circuit’s temporary response that will die out with time. Operational amplifiers.
