10.11 SUMMARY

• Circuits containing energy storage elements have memory in time-domain. They are described by linear ordinary differential equations with constant coefficients. We need to know the forcing function beginning from some time instant along with the initial conditions in the circuit specified at that instant to solve such differential equations.
• We focussed on series RL circuit in this chapter. RL circuit is described by a first order linear differential equation. The past history of an inductor is contained in a single initial condition specification in an RL circuit.
• The solution of the differential equation describing the inductor current in an RL circuit contains two terms – the complementary function and the particular integral. ...
