Input energy = output energy + losses
Where the energy enters the system.
You divide useful output energy by the input energy. Or equivalently, useful output power by input power.
Yes. Yes. No.
With energy input
Energy release is to condensation as energy input is to vaporization. Vaporization requires energy input to happen, while condensation releases energy.
The energy input is always greater than energy output.
Input energy = output energy + losses
The movement of molecules without the input of energy is passive transport.
Where the energy enters the system.
Electrical energy
You divide useful output energy by the input energy. Or equivalently, useful output power by input power.
yes. yes. no
Yes. Yes. No.
the input isand the outpt is
Efficiency = ( useful energy output / total energy input ) x 100
