AC circuit steady state expression

Click For Summary
SUMMARY

In an AC circuit at steady state, a capacitor behaves like a short circuit while an inductor behaves like an open circuit. This means that the inductor does not simply result in a zero output; rather, both components exhibit frequency-dependent impedance. Understanding these characteristics is crucial for analyzing AC circuits effectively.

I know that in an AC circuit at the steady state a capacitor behaves like a short and inductor behaves like an open. Since the inductor is open wouldn't that just mean the answer is 0?

No, those characteristics apply to DC steady state for those components. For AC, the components exhibit impedance that depends upon frequency.
