Problem
Circuit A contains a 1.0kΩ resistor in series with a 1.5μF capacitor connected to a 6.0V battery. Circuit B contains a 2.0kΩ resistor in series with a 0.50μF capacitor connected to an identical battery. Immediately after each switch is closed, which circuit will reach one-half of its final capacitor voltage first? Answer with “Circuit A” or “Circuit B.”
