📚 Topic Summary
An RC circuit contains a resistor (R) and a capacitor (C) connected in series or parallel. When a voltage source is applied, the capacitor charges or discharges over time. This charging and discharging behavior is called transient behavior because it's not the steady-state condition. The time constant, denoted by $\tau = RC$, governs how quickly the capacitor charges or discharges. Understanding this is crucial for designing circuits that need timed responses.
