2) the flow of current is always from the postive (+) terminal to the negative (-) terminal.

3) ammeter is a device used to measure current flowing in a circuit.

4)Electric Current : an electric current is the flow of electrons through a conductor. quantitatively, current (I) is defined as the charge passing through a conductor in unit time.
