Here's a question for the electronic wizards here at the YT site. I remember ohms law but although it's involved here I think, my actual question relates to something else. Let's say that we are passing a DC current through a ceramic wire-wound resistor to ground. Let's suppose we have a circuit with 6 DC volts and 4 amps going into the resistor. The resistor is grounded. Which resistor would get hottest (as in temperature), a 3 ohm resistor or a 10 ohm resistor? So my question is, under identical conditions, would a low ohm resistor or a higher ohm resistor generate more heat? And if you can, maybe you could supply reason(s) for your answer. Thanks in advance.
