Electricity So Far

Electricity is a form of energy resulting from a current. So far i have learned 10 vocabulary words that are atoms, conductors, current, electricity, electrons, generator, insulators, mechanical energy, neutrons and finally, protons. All these vocabulary words are a part of what is electricity and what electrocity does. I'm comfused about how heat gets transfered to electricity. I don't know how that process works. I'm getting better at describing how i can transfer energy into another object.
