Electricity works by providing ‘force’ to electrons also known as potential. Electricity is defined as the movement of electrons. Amps are the flow rate measured in current and the resistance of a circuit is referred to as Ohms.  There are many sources to generate electricity such as solar, wind, electromechanical generators, steam turbines, etc. Electricity can be made in 2 forms:  AC (alternating current)  DC (direct current) All the power coming into a house from the street is AC power, this is what runs around a home to provide power to all devices. Electronics such as computers work on DC current where a transformer is required, this is generally a small box which plugs into a powerpoint which converts the electricity from AC to DC.  Solar power creates DC current which can be stored in batteries. This stored power can be converted to AC power through a transformer.
