Learn an alternative solution technique for capacitor circuits that remains effective regardless of the source turning on or off. For example, when a capacitor behaves as an open circuit under steady-state conditions. This method ensures detailed understanding and calculations, as demonstrated in finding the voltage across a capacitor in different scenarios. Enhanced comprehension of circuit analysis with independent solutions for dynamic components.

Alternate Equation • Independent of whether the source in the circuit turns on or off at t = to.
Because a capacitor acts like an open circuit under steady state conditions t ≤ to t >> to vcinitial = vin = 3 V vcfinal = vin = 2 V The current flowing through the resistor in both cases is zero. Therefore, the voltage across the capacitor, vc = vin, from KVL (sum of voltages around a loop is equal to zero)
