In a driven RL circuit with a DC source, the total current can be written as i(t) = i(infinity) + [i(0+) - i(infinity)] * e^(-t/τ). What does the term i(infinity) represent?
Explanation
The formula for the complete response of a first-order circuit elegantly combines all the necessary components: the initial value i(0+), the final value i(infinity) (which is the forced response), and the time constant τ. The term i(infinity) represents the steady state that the circuit settles into.
