The flow of electrons moving in an electrical conductor with a certain velocity called the electric current (I). The emergence of electric current because there is a potential difference at two ends of a conductor. While the potential difference in the two conductor due to one end of the conductor to get a force that drives the electrons to move.

Electric current will only occur in a closed circuit. Unit to measure the electric current is called the Ampere or abbreviated with the letter A. One coulomb charge of an electron moving through a conductor of a circuit in one second is called an Ampere. The relationship between electrical current (I), the amount of electron charge (Q), and the unit time (t) is written with the formula


Where:
- I is the electric current (in Ampere)
- Q is the electron charge (in units of coulombs)
- T is time (in seconds)

Sample questions:
What is the size of an electric current that flows when the number of electrons of 60 coulombs in a closed circuit for half a minute?

Completion:


electric currents flowing at 2 Amperes.
