Resistance of Wire

Aim: - In this experiment I will be determination out the electricalal rampart of a telegram in which its space is the variable. I will be analyze the process of how more than the resistance changes due to the increase of the length of the wire (constant wire). Electrical Current Electric accredited is the estimate of counselling strike past a abandoned tip in all electric circuit, measured in coulombs/seconds, which is named amperes. In most DC electric circuits, it can be assumed that the resistance to topical flow is constant so that the new in the circuit is related to voltage and resistance by Ohms law. I = V/R The unit of electric charge is the coulomb. general matter is make up of atoms which have positively charged nuclei and negatively charged electrons surrounding them. Charge is made as a multiple of the electron or proton charge. as well as the rate flow of electric charge is called electric current and is measured in amperes. Basics In a condu ctor, electric current can flow freely and in an dielectric it cant. Metals such as squealer ar good conductors turn most non-metallic solids are good insulators having truly high resistance to the flow of charge with them. Conductor implies that the outer(prenominal) electrons of the atoms are loosely cut back and free to move through the material.

Most atoms hold on to their electrons tightly and are insulators. In copper, the outer electrons are essentially free and strongly freak each other. Cross-section of copper wire: potential Voltage is a measure of the step of push given to electric charge in a circuit. If on t hat point is no push electrons will not be ! move around the circuit. This voltage would normally be supplied by a electric cell battery or power pack. Voltage and energy are link up the more you push...
