He developed this concept via experiments were he was able to collect "positive" and "negative" charges which became the common naming or conventional current flow untilit was discovered that protons don't move.

Flying a kite, Franklin perceive the lightning rays and decided to realize an experiment: he would get his kite, tie it up to a key and notice how it transmitted to the key.

The Coulomb Law was published by Charles de Coulomb, and he claimed that the force between two charged particles, regarded as point charges Q1 and Q2 a distance d apart, is proportional to the product of the charges and inversely proportional to the square of the distance between them. This law was essencial for the advances in the eletricity studies in physics. The formula for the law is: Fe=(kq1q2)r²

By putting a compass on top of a wire that transported a current, when he noticed that there was a change on the compass' pointers.
-
1st law is that the potential difference applied between its two point is equal to 1 volt
2nd law is R=pL/A -
The concept of electric field was created by Michael Faraday. Electric field, as being a property that describes the space surrounding electrically charged particles, and this electric field exerts a force on other electrically charged objects.
-
He helps the development of the final verion of the electric field, the version we know and study nowadays.

Gustav Kirchhoff created two circuit laws: The 1st law states that the sum of a current into a junction is equal to the sum of the current away from the junction.
The 2nd one states that in a complete circuit loop, the sum of the potencial differences in the loop is equal to zero. -

The left hand rule is used to discover the direction of a magnetic force.
The right hand rule is used to discover the direction of a magnetic force on a moving charge. -
He discovered that current flowed from the negative pole of a power supply to the positive pole. Thus, discovered that the conventional current was the wrong way around.
