'''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''. Larger currents require thicker conductors.

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. Larger currents require thicker conductors.
