Internal resistance survey We conduct the following investigation, the aim is to find the internal resistance of the lemon battery, I will make it myself. Variables that may affect my experiments are as follows: · Lemon size - I will experiment within an hour to allow me to use the same lemon to get all the results Size of the metal electrode - I use exactly the same experiment Center electrode - Any cable length - Use the same wire throughout the experiment. Once data is gathered, it will not break circuit resistance · Circuit - change this

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.

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.
