Current And Resistance Of A Wire And The Affects When The Length Changes
Current and Resistance Physics Investigation
Aim:
Investigate how the length of a wire affects the current and resistance of a wire.
Prediction and Hypothesis:
I think as you increase the length of the Constatan wire, you also increase the amount of resistance. The current is the flow of electrons; the current is dependent on the amount of voltage, which is applied. Voltage is the push given to the current. The current has to go through a circuit, which contains resistance so if you increase that push you also increase the flow of the current. All materials have a slight resistance to electricity factors affecting the resistance are: Length, Voltage & Temperature and Surface Area
Length
The diagram shows the happenings of a wire
the blue dots represent some of the negative
electrons which leads to a lower voltage output,
when the length is increased.
Voltage & Temperature
Temperature has an affect on the experiment as the voltage has control over......
