What means "steady state"?

I´m trying to understand what mean exactly the steady state and why is so important. I had see that is used in some protocols for I-V currents and I don´t get the point how to calculated it and how to interpret it

My understanding is that you

My understanding is that you define a steady state and then look at changes in relation to the steady state.  So you would pick a voltage for steady state in a voltage clamp experiment.  Also, there are steady state and voltage dependent inhibitors of ion channels.  The voltage dependent require opening and closing of the channel in order to inactivate.
