Answer:

Options: 1, 3, 5, 7, 8

Explanation:

In steady state at the point when the current at each point in the circuit is  

consistent (doesn't change with time).  

  • In numerous viable circuits, the steady state is accomplished in a brief period of time.
  • In the steady state, the charge (or current) streaming into any point in the circuit needs to equivalent the charge (or current) streaming out which is  Kirchhoff's Node or Current law.
