It is used to control the amount of voltage and/or amperage in a circuit. Everything in a circuit causes a resistance. Resistance is measured in ohms. Resistance occurs when the electrons traveling along the wire collide with the atoms of the wire. These collisions slow down the flow of electrons causing resistance...

Resistance is a measure of how hard it is to move the electrons through the wire. The resistance of a wire depends on the number of collisions the electrons have with the atoms, if a larger number of collisions occur, the resistance of the wire will increase. To calculate the resistance of a wire, I will use ohms law, which is: V=IR, therefore R=V/I...
