A simple circuit with a current source.
The circuit symbol for an ammeter
An analog 0 to 1 mA panel meter

Current is a measure of how much electricity is flowing and is measured in Amps (A) and its symbol is I. Electrons carry a negative charge, hence they move from the more negative end of the circuit to the more positive. Current flow from positive to negative is termed conventional current.
