Conductor Investigation Experiment LabReport
Introduction
This experiment is about to test how will the nichrome wire effect the ampere of the electric current. All the possible factor that will effect to the volt of the current • The Length of the wire • The Diameter of the wire • Temperature • Magnetism
Aim
To determine the effect of the length of the wire on the ampere of the electric current.
Hypothesis
Nichrome is an alloy(a metal made by combining two or more metallic elements) that is made out of 80% nickel and 20% chromium. I know that it is a resistant material that will slow electric current down, therefor, it will produce heat and some light. I think that the more nichrome wire that we use the ampere will be lower, I think that is because the longer the wire is, the more electricity that the wire will slow down.
Apparatus
- Power Supply - Wires (Leads) - Alligator Clips - Ammeter - Nichrome Wire (20 Gauge)-(different length) (2 cm, 4 cm, 6 cm, 8 cm, 10 cm)
Method
1. Set up the power supply. 2. Connect the ammeter and the nichrome wire. 3. Cut 5 different length of wire . 4. They all need to be 2,4,6,8,10 cm long. 5. Test the different length of the wires. 6. Record the results. I will measure the ampere that is shown on the ammeter
Fair Testing
Controlled variable :The same voltage from the power supply, same wires, alligator clips, ammeter. Independent variable : The length of the nichrome wire. Dependent variable: The ampere of the current. This is a fair test because there is only one thing that is different in the experiment, which is the length of the nichrome wire.
