Final answer:
The unit used to measure electric current is the ampere (A). One ampere is equivalent to one coulomb of charge moving in one second (C.s-1).
Step-by-step explanation:
The unit used to measure electric current is the ampere (A).
One ampere is defined as the amount of electric current that will produce an attractive force of 2.7 x 107 newton per meter of separation between two parallel wires with an electric current running through them.
The symbol used to represent current is I and it is measured in amperes (A). One ampere is equivalent to one coulomb of charge moving in one second (C.s-1).
