Calculate the parasitic resistance of a 5.7-in. PCB trace having a width of 2.5 mm and a thickness of 2 mils. If this trace feeds a 2.5-V DC signal to a 1-? load resistance, what will be the error of the voltage at the load as a percentage of the source voltage? (Assume a zero-resistance current return path.) How much power is dissipated by the trace?
