Which component?

[iCosine]

I've been assigned a project by my intern company to design something to test the current carrying capacity of my company's product. Let's call it UTI. The UTI has a resistance of 0.035 ohm at room temperature and it will change when there's a change in current due to heat. So I would like to know which component in the multisim can I use to simulate this product as to plot the current vs resistance graph. Thanks!

Hello,

The problem is to be able to simulate this you need to already know how your product will change. Even if we had a component that changed resistance due to heat (sounds like a thermistor), we don't know by how much or how long or how current affects the heat passing thourgh your component. So this simulation will likely result in unwanted results. I would suggest to use your product and stress test it in real life and collect the data of the resistance and current using commonly used equipment (ammeter? voltage/current source?)

Kind Regards,
