VDA - Electricity (Part 1/3)

The science dealing with the physical phenomena arising from the existence and interaction of electric charge

• Electricity

• Electric charge

• Power

The intrinsic property of matter giving rise to all electric phenomena, occurring in two forms arbitrarily given positive and negative algebraic signs and measured in coulombs

• Electricity

• Electric charge

• Power

The product of potential difference and current in a direct-current circuit

• Electricity

• Electric charge

• Power

The SI unit of power, equal to one joule per second or to the power represented by a current of one ampere flowing across a potential difference of one volt

• Watt

• Wattage

• Amperage

An amount of power, esp. the power required to operate an electrical device or appliance, expressed in watts

• Ohm

• Wattage

• Amperage

The strength of an electric current measured or expressed in amperes; analogous to the rate of water flow

• Ohm

• Wattage

• Amperage

A unit of power, equal to 1,000 watts

• Kilowatt

• Kilowatt-hour

A unit of energy, equal to the energy transferred or expended by one kilowatt in one hour; a common unit of electric power consumption

• Kilowatt

• Kilowatt-hour

Potential difference or electromotive force expressed in volts; analogous to pressure in water flow

• Voltage

• Current

• Ampere

• Resistance

The rate of flow of electric charge in a circuit per unit time, measured in amperes

• Voltage

• Current

• Ohm

• Resistance
