I use a 1-V voltage to apply to a 200-ohm resistor, so the power consumption on the resistor is V^2/R=5mW. I measured the temperature close to the resistor hoping that the ambient temperature can rise.
However, it does not increase the temperature. How can I detect the temperature variation if the resistor consume 5mW energy? Thank you.
