Unit of work of amperage. The definition of this unit.

The electric current itself is of no practical importance. What matters is what he does. The work shows how the energy of an electric current is converted into other types of energy – mechanical, thermal, etc.

The work of an electric current is equal to the product of current strength and voltage and time of current flow in the circuit.
A = IUt, where

A – work (unit of measurement – 1 J);

U – voltage – (unit of measurement – 1 V);

I – current strength – (unit of measurement – 1 A);

t – time – (unit of measurement – 1 s).
