The term 'Unit of Electric Current' can be broken down into six different solutions: AMPERE (6 letters), Amp (3 letters), Volt (4 letters), Farad (5 letters), Watt (4 letters), and Ohm (3 letters). AMPERE is the SI unit of electric current, which is the rate of flow of electric charge. Amp is a common abbreviation for AMPERE. Volt is the SI unit of electric potential difference, or the difference in electric potential between two points. Farad is the SI unit of electrical capacitance, which is the ability of a body to store an electrical charge. Watt is the SI unit of power, which is the rate at which energy is transferred, used, or transformed. Ohm is the SI unit of electrical resistance, which is the opposition to the flow of electric current.
