What is Electric Current?

Electric current is a flow of charged particles through a conductor. Electric charge is mostly carried by the electrons and protons within an atom. Protons have a positive charge, while electrons have a negative charge.

What is Electric Circuit?

A continuous and closed path of an electric current is called a circuit.

• The point where the electrons enter an electrical circuit is called the “source” of
electrons.
• The point where the electrons leave an electrical circuit is called the “return” or “earth ground”.
• The exit point is called the “return” because electrons always end up at the source when they complete the path of an electrical circuit.

What is Ohm’s Law?

Ohm’s law states that the current through a conductor between two points is directly proportional to the voltage across the two points. Introducing the constant of proportionality, the resistance, one arrives at the usual mathematical equation that describes this relationship:

V ∝ I
V = RI

Where: I = The current through the conductor in units of amperes
V = The voltage measured across the conductor in units of volts and
R = The resistance of the conductor in units of ohms.
