Measure Trace Resistance and Blow up Traces

Goal

In this lab we will learn how to measure trace resistance using the 2 wire DMM method and 4 wire method. We also understand what constant current and constant voltage in power supply. The measured resistance values of the traces are compared with the estimated values. We will also understand how much can a particular trace width of 6mil, 10mil, 20mil and 100mil can withstand a current in it.

Special Board

I have included all the calculations for measuring the resistance of the trace width in a detailed way here.
