What is electricity?
Electricity is the flowing of electrons from a higher electric potential to a lower one (or alternatively, flowing of electron holes in the opposite direction). The flowing electrons can perform work, ranging from heating a resistive element in a light bulb to turning a motor through a magnetic field.
