The SI unit for metering an electric current is the ampere, which is the stream of electrical charge across a surface at the ratio of one coulomb for every second. Electric current is gauged using a device called ammeter. Current is the flow of electrons that cause the phenomenon known as electricity and powers our appliances and machines. Current is quantified in amps and resistance is measured in ohms.

The unit of measure for current is amperes. To measure current, you must connect the two leads of the ammeter in the circuit so that the current flows through the ammeter. The best way to measure the current flowing through a simple circuit is to insert your ammeter into the circuit.
