2. Two small light bulbs, each with a resistance of 2 ohms, are connected to a capacitor and: 12-volt battery as shown in the circuit diagram below. The switch is then closed. (NB: Every capacitor acts like a wire when first connected to a voltage source, but after enough time has passed and the capacitor plates become saturated with charge it acts like a break.) A) Determine the power dissipation of each bulb the moment after the switch is closed. B) Determine the power dissipation of each bulb once the capacitor has been fully energizea t C) Describe how the brightness of each bulb changes with time after the switch is closed.
