Calculating energy efficiency
{"Image DocumentName": "Calculating energy efficiency", "Image ImageDescription": "The efficiency of an energy transfer can be calculated using this formula: total energy input. useful energy output. %Efficiency = x 100. This bulb converts 200 J of chemical energy form battery into 10 J of useful light energy: Efficiency of bulb = = 5% x 100.
