Prim 4 Concept 3.1 Part 2

................... is a way to describe or represent the energy flow from the source to the devices.

• Energy conservation law

• Energy chain

• Waste energy

• Energy

................... is the energy that is not helping in the main function (the device does not use).

• Energy conservation law

• Energy chain

• Waste energy

• Energy

................... The energy is neither created nor destroyed but transforms from one form to another continuously.
