Final answer:
In the context of Physics, when a 6-volt battery provides a coulomb of charge to a bulb's filament, it delivers 6 watts of power, according to the equation P = IV.
Step-by-step explanation:
The question revolves around the concept of electrical power and its relationship with current and voltage in a circuit, which is a key topic in Physics.
When a 6-volt battery is connected to a bulb, the amount of power provided to the filament when a coulomb of charge flows is determined by the power equation P = IV, where P represents power in watts, I is the current in amperes, and V is the potential difference or voltage in volts.
In this case, the correct answer is 6 watts, because 1 coulomb per second is 1 ampere, and multiplying the current (1 ampere) by the voltage (6 volts) gives 6 watts of power.
