A battery changes chemical energy into electric (electromagnetic) energy.
The basic idea is that electrical energy is converted into chemical energy, which is what the battery stores.
electrical energy into chemical energy
In a battery-operated can opener, electrical energy from the battery is converted into mechanical energy to rotate the can opener blade and open the can.
electronic energy.
Electrical energy -> Sound energy.
Electrical energy is transferred from the charging source to the phone battery. This electrical energy is converted into chemical energy and stored in the battery for later use.
Electrical energy -> Heat energy -> Sound energy.
The chemical energy in the battery is converted into electrical energy to power up the phone.
A fuel cell (like a battery) converts chemical energy to electrical energy. The main difference being in the fuel cell the energy rich chemicals are continually being resupplied, while in a battery the energy rich chemicals were put in when the battery was initially assembled and cannot readily be replaced or resupplied.
potineal energy is taken place in a flashlight then is turned into termal and electrical energy
The electrical energy is converted to heat.
