This software models the passing of a voltage through metal wires of varying dimensions to see how resistance and current varies until a power equilibrium is reached, when the power going into the circuit equals the power coming out via heat emission. It is designed to support the teaching of Science and Physics at GCSE and A Level.
The model takes into account the resistivity and temperature coefficient of the metal.
The following parameters can be varied within the model:
- Voltage applied;
- Length and diameter of the wire;
- Room temperature;
- The required sample interval.
As these parameters are varied, the number of samples that will be taken is displayed so that the optimum number for a particular experiment can be selected. The temperature, resistance, power in and out and current are calculated for each sample.
Parameters can be adjusted and the metals list modified to the user’s specification. These new settings can be saved in a file for later use.
The results can be printed and also exported as a CSV file for further analysis or graphing.
The application is supported by a comprehensive help file which includes guidance on how to generate the required number of samples.
