Principles of electricity-Ohm´s law

Voltage: It is "the force" with which the positive pole attracts electrons from the negative pole. It is measured in volts. For example, a single battery has 1.5 V, a flask battery has 2.5 V and a rectangular battery has 9V.

Intensity: It is the flow of electrons that crosses a section of the conduits. It is measured in amperes. 1 Ampere is 1 Coulomb/second, where 1 Coulomb is a package of 6.25x10^18 electrons.

Resistance: They are elements that interrupt more (1 MOhm) or less (1 Ohm) the electric current.

The relationship between these concepts is given by Ohm's Law:


I= V/R
