- Energy Efficiency
- Sankey Diagrams
- its efficiency =15/100 =0.15
- Its percentage =0.15 x 100% = 15%
- Electrical Appliances
- They transfer electrical every into useful energy at the flick of a switch
- Each appliance is designed for a particular purpose
- For example and amplifier for speakers
- Each appliance is designed for a particular purpose
- They transfer electrical every into useful energy at the flick of a switch
- Using electrical energy
- E = P X T
- E- is the energy transferred in kilowatt hours
- P- is the power in kilowatts
- T- is the time taken for the energy to be transferred in hours
- Cost effectiveness matters
- The capital costs, the running costs, environmental costs
- cost efficnecy means getting the best value for money
