Transcription: Electricity is a flow of negative charges called electrons. Electrons are particles that form a part of all atoms. These electric charges are measured in units called coulombs. Electricity is a very versatile form of energy because it can be converted into many other forms of energy. There are two types of electricity. Direct current, DC, which flows in one direction only, and alternating current, AC, which changes direction many times every second.
