Explanation :
An electric Motor is used to convert electical energy to mechanical energy.
Electric bell uses electric energy to make sound which is sound energy.
An electric bulb uses electricity to produce light and heat which is light and heat energy.
A photo-cell uses suns energy or light energy and produces electricity e.g solar cells.
A steam engine uses heat energy to produce mechanical energy e.g Steam engines in trains.
