What is the term for the ratio of useful energy that comes out of a device to the total energy that went in?
The term for this ratio is "efficiency". It is used to measure how well a device converts input energy into useful output energy.
Percentage of energy that is used by a device to perform work is called?
That is called the "efficiency" of the device.
Rate at which an electrical device converts energy from one form to another is called?
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.
What device converts heat energy to work?
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.
What is electrical energy transferred to?
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.

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.
How do you find the efficiency of an electrical device?
To find the efficiency of an electrical device, you can use the formula: Efficiency (%) = (Output Power / Input Power) × 100. Measure the input power, typically in watts, that the device consumes and the useful output power it provides. Efficiency indicates how well the device converts electrical energy into useful work, with higher percentages indicating better performance.

What is the name of a system that converts thermal energy into a form of useful mechanical or electrical energy?
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.
What type of energy does a TV convert to?
Converts Electrical energy into the useful energy, light and sound. There will be some unwanted heat energy as well
If you have a device that has an energy efficiency of 0.7 and you put in 150 units of energy how many units of useful energy will you get out of it?
To calculate the useful energy output, multiply the input energy by the energy efficiency. In this case, with an energy efficiency of 0.7 and an input of 150 units, the useful energy output would be 0.7 × 150 = 105 units. Therefore, you would get 105 units of useful energy from the device.
What is the efficiency of a device that gives you 100 units of useful energy for every 100 units you put in it?
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.
What does efficiency compare energy output with?
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.
