Temperature and Electricity Abstract

Many factors are known to affect how well a metal conducts electricity. Temperature is one factor that affects the resistance of a conductor.

Purpose: This experiment tested to see how varying temperatures affects the resistance of copper.

Hypothesis: The prediction was that there would not be a dramatic difference in the resistance since the temperature range was not super high or super low.

Procedure: In this experiment, a copper wire was put in varying temperatures from 0 to 260 degrees Celsius and measured with a multi-meter to find the resistance and checked using an equation. The resistances of the copper wires were compared to the temperature of the wires.

The multi-meters used could not show the resistance of the wire in room temperature and the cold temperature. An equation was used to find the very small numbers and to double-check the readings.

Conclusion: This data supported the hypothesis in that there was not a huge difference between the varying temperatures. They were different by a few mili-ohms. What can be conclude, is that temperature does have an impact on resistance. Also using a multi-meter is not always an accurate tool to use since it often fluctuated.

Because of this, it was necessary to double check measurements. Knowing this can influence future research in designing better conductors and more accurate multi-meters.
