Hi guys,
I had a question about heating up resistors and thermal lag... I have a control system which uses thermocouples as the feedback sensors, and I alter the voltage across the resistor (AC) according to error...
Now, I understand that there is thermal lag in terms of the resistor heating up.. my question is as follows : will it matter whether the voltage applied is AC or DC ? in other words, is it possible to decrease the lag time in heating up the resistor if DC is used instead of AC ?
Thanks
