2.- ELECTRIC CURRENT
Electric current is the continous movemen of electrns through a material. Not all materials allow this.
Current flows when there is an electron imbalance between two points, it stops once the charge is balanced, just like water equalizing between two connected containers.
Conductors
Allow current to flow.
Metals like gold, silver, and copper
Inductors
โขBlock current flow.
โข Plastic, wood, ceramic, and air.

7.- OHM'S LAW
Formulated by Georg Ohm, this law expresses the proportional
relationship between voltage, current and resistance
Example:
A bulb with 220 ฮฉ connected to a 4,5 V battery has a current flowing through it of 20 mA. ๐ = ๐ผ โ ๐
โ ๐ผ = ๐ ๐
= 4,5 ๐ 220 ฮฉ = 0,02 ๐ด = 20 ๐๐ด
