This is a picture of my iPhone Charger. This charger is able to convert AC power into DC power. The difference between AC (Alternating Current) and DC (Direct Current) power is that AC is power that can move in either direction, and DC is power that can only move in one direction. This charger, like many other household appliances, has a voltage of 120 volts. Voltage, otherwise known as electric potential difference, is the potential difference between two points. Amperes is the SI unit of electric current that is equal to the amount joules per one coulomb. Voltage and Amperes are found on many utilities around the world. Many countries have different amount of voltage per household.
