Current in a circuit flows:

Current in a circuit flows in a direction from high potential to low potential.

What is current, and how it flows?

An electrical phenomenon is caused by the flow of free electrons from one atom to another. The characteristics of current electricity are opposite to those of static electricity. Atoms of metal are made up of free electrons, which freely move from one atom to the next. If an electron is added to a wire which is made up of aluminium or copper, a free electron is attracted to a proton to be neutral. Forcing electrons out of their orbits can cause a lack of electrons. Electrons, which continuously move in wire, are called Electric Current. Current flows from positive to negative, and electron flows from negative to positive.

  • The instrument used to measure the current is called an ampere meter or ammeter.
  • There are two kinds of current electricity: direct current (DC) and alternating current (AC).
  • One ampere of current represents one coulomb of electrical charge (6.24 x 1018 charge carriers) moving past a specific point in one second.
