A photo voltaic cell
The term for this ratio is "efficiency". It is used to measure how well a device converts input energy into useful output energy.
That is called the "efficiency" of the device.
The rate at which an electrical device converts energy from one form to another is called efficiency. It is typically expressed as a percentage and is a measure of how much of the input energy is converted into useful output energy.
A heat engine, such as a steam turbine or internal combustion engine, is a device that converts heat energy into mechanical work. This process typically involves the expansion of a high-temperature gas or fluid to produce movement that can be harnessed to perform useful tasks.
I assume you mean what it is converted to. It can be converted to many different types of energy; that's one of the things that makes electrical energy so useful. (The other useful feature is that it is relatively easy to transport.) For example, a heating device can convert electrical energy to heat; a speaker converts it to sound; a television set or a computer monitor converts it to light; etc.

A system that converts thermal energy into a form of useful mechanical or electrical energy is called a heat engine. This process involves using the temperature difference between a heat source and a heat sink to produce work, which can be used to generate electricity or perform mechanical tasks.
The efficiency of the device is 100%. This means that all the energy input into the device is converted into useful energy output without any loss.
Converts Electrical energy into the useful energy, light and sound. There will be some unwanted heat energy as well
if you mean in terms of energy then it refers to a device that transfers more useful energy than it wastes if you mean in terms of energy then it refers to a device that transfers more useful energy than it wastes
Efficiency compares the useful energy output of a system to the total energy input. It provides a measure of how well a system converts input energy into useful output energy.
Friction converts mechanical energy into heat, which is rarely useful, and which can never be recovered in its entirety. Due to conservation of energy, this heat energy is not available for other things, i.e., for useful work.
