Investigating Resistance In a Wire

Investigating resistance in wiring planning In this survey we understand how the wiring of various materials affects the resistance of a series circuit. In order to test whether this works, I use equipment such as a power supply box to provide the necessary energy. I also use a voltmeter and ammeter to test my resistance. As shown in the following figure, the relationship between current, voltage and resistance can be expressed by Ohm's law. [IMAGE] This means voltage (V) = current (I) × resistance (R).

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. In other words, they lead me electronically. 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.

Because other factors such as temperature are difficult to control and change, I decided to investigate the influence of wire thickness on resistance. There is not enough material to study how the material affects wire resistance. The effect of wire thickness on resistance is an effective experiment. The drawing can be drawn easily, a wide range of results can be obtained, and the result can be easily recorded. The thinner the wire, the less the path of electrons in the wire, so the current will not flow easily. This will increase the resistance because the energy does not diffuse too much. If the thickness of the wire is thick, more electrons can pass through the wire, so the resistance becomes smaller. Due to the large diameter of the wire, atoms from the metal can not collide or collide with as many electrons as possible.
