With this definition we can say that an electric current has an intensity of 1 amp when a load of 1 colombium passes through a section of the conductor in 1 second. Ampere is often shortened to Amp and is abbreviated by the unit symbol A. The electrical conductivity of a material is the measurement of the ability of the material to allow for the flow of electrical current.
One ampere is equal to a flow of one coulomb of charge per second.
I V R Corresponding units. The standard metric unit for current is the ampere. Ampere A volt V ohm O This formula is derived from Ohms law. The voltage V in volts V is equal to the current I in amps A times the resistance R in ohms O.
