What is the transformation of energy happens in the following? 1. cellular phone

Answer 1

Energy transformation is when energy changes from one form to another – like in a hydroelectric dam that transforms the kinetic energy of water into electrical energy. While energy can be transferred or transformed, the total amount of energy does not change – this is called energy conservation.

Answer 2

Answer:

When the circuit is complete and current is being drawn from a cell, chemical energy is converted into electrical energy. A cell can be called a device, whose role is to convert chemical energy into electrical energy.
