Question

A generator makes 3.45 kilojoules (kJ) of energy during each minute of

Answer 1

The total energy produced by the generator is 3.45 kJ. Of this energy, 2.23 kJ are lost because friction and electrical resistance, so this amount of energy is converted into thermal energy. This means that the rest of the energy is available as electric energy, and it is equal to:
$E=3.45 kJ-2.23 kJ=1.22 kJ$
