The rate at which an electrical device converts energy from one form to another is called electrical power. The rate at which electrical energy is changed to another energy form electrical power.
yes is was a labor-saving device
A torch (flashlight) is a convenient lighting device, where the energy source and the illumination are provided in a utilitarian form. (Headlamp, handheld, etc.)A complete electrical circuit is needed to operate the device, and an integral switch completes the circuit.The batteries naturally have their own built-in insulation to prevent premature discharge, and otherwise the circuit, as with all other electrical circuits, needs insulating from accidental discharge.
Efficiency
Anything device can transform electrical energy into other form of energy. This is called an electrical load.
A flow of electrons is needed to have a current. And there (usually) must be a complete circuit. And you need a voltage to make the current move around your circuit. All tied up in Ohms Law - which I'll leave to you.
When two or more electrical components are connected, what they form is usually called a device.
It is the component that brings the potential in the form of voltage to the load.
