Answer:
When a switch is closed, electrons move through a circuit from the negative side of a battery to the positive side
Explanation:
Not sure if this helps but, Electrons flow from negative (where they repel each other) to positive (where they are attracted). As electrons flow through a circuit, they need 'something to do'. In many cases, that something is to light a bulb or heat an element, such as an element on a stove. So, the energy of an electron can be converted to heat or light.
Hopefully this helps! :,D
