The Resistance of a Wire

Conductor Resistance All conductive materials have electrical resistance when energized. Copper has the least metal and is also the cheapest, so it is used in all electric appliances to increase efficiency. Materials such as lead are not used for electric wires because of their high electrical resistance. Goal === The purpose of the experiment is to investigate how wire length affects resistance. Prediction ========== We expect to increase resistance as the length increases.

In this survey we investigate the impedance of the wire against the current and identify the factors that affect wire resistance. There are five main factors that affect wire resistance. They are as follows: 1) wire material. 2) Wire length 3) Wire thickness (diameter). 4) Temperature of the wire 5) Voltage of the circuit However, my survey shows only two different factors that affect wire resistance.

In this experiment weather can be seen, but the thickness of the wire affects the resistance of the line. Also, you can see that wires of different lengths affect wire resistance. I attach a wire to the circuit and use an ammeter and voltmeter to record my results. Current is the flow of electrons along conductors such as metal wires. The battery pushes electronic equipment toward the circuit. When the circuit is disconnected, no electrons flow. Since the electrons are not destroyed, the current is not exhausted. The bulb has a high electric resistance and resists the flow of electrons, so we make a light bulb. Measure the current in amperes using an ammeter

Examining the resistance of a wire is the name of the wire's resistance to the tendency of electrons to travel through the wire. The greater the resistance generated by the electron, the greater the voltage required to drive the current through the wire. The resistance value is defined by the following equation. Resistance on resistor R (R) = p · db <Current through wire (I) <Tab /> Important factors have many factors that can influence. Temperature, current, line thickness, line length, line resistance. When the temperature rises, atoms in the wire begin to vibrate. That is, since they react electronically, the temperature affects the resistance. The problem with this method is that it is difficult to change the temperature of the wire and keep it at the same constant temperature.
