Energy efficiency calculations worksheet gcse.
Energy is a key principle in physics as it allows work to be done.
Modern energy saving lamps.
Worksheet on calculations using the efficiency equation.
Efficiency is a measure of how much work or energy is conserved in a process.
The efficiency is the energy output divided by the energy input and expressed as a percentage.
The rate at which energy is transferred is called power and the amount of energy that is usefully transferred is called efficiency.
Also links in with other areas of p1 3 other than energy efficiency.
A simple worksheet for pupils to do in class or at home.
The efficiency of a device is the proportion of the energy supplied that is transferred in useful ways.
Suitable for ha year 9s or gcse students.
The efficiency can be calculated as a decimal or a percentage.
In many processes work or energy is lost for example as waste heat or vibration.
