A group of campers travels to a cabin which has no electrical power. In order to provide for a heater and lights, which device w
larisa [96]

Answer:A generator is the appropriate device to be used.

Explanation:

A generator is a device which transforms mechanical energy to electrical energy.

The different parts of a generator includes:

- Engine, alternator, fuel system, voltage regulator, lubricating system, cooling and exhaust system, Battery charger and control panel.

The generator works on the principle of electromagnetic induction which states that

that the above flow of electric charges could be induced by moving an electrical conductor, such as a wire that contains electric charges, in a magnetic field. This movement creates a voltage difference between the two ends of the wire or electrical conductor, which in turn causes the electric charges to flow, thus generating electric current.

Therefore, the use of a generator is the best device for the campers to provide electrical power source for their heaters and light in the cabin.
