You have a simple circuit consisting of a battery and a lightbulb (you can imagine that this circuit is contained within a flashlight). If the total potential difference provided by the batteries in this circuit is 6V, and if you measure the current to be 23.04mA, what is the resistance of the light bulb (created by the thin wire which composes the filament) in units of Ohms?
