I hope no one minds if this is a stupid question but does the physical size of a resistor effect the measurable temperature of heat dissipated? I ask because I'm thinking of engines and a big block compared to small. One of each engines creating the same power theoretically creates the same amount of heat yet the small block will run hotter--all things being equal. Each engine has inherent pros and cons but because engines have a "Goldilocks" operating temperature the big block is generally considered more efficient. The total dissipated heat may be equal but the operating temperatures are not the same. Does the same hold true for a resistor? Can the physical size of a resistor effect its working life? Controlling engine compartment temperature to designed parameters is a fairly new design and engineering consideration for engine efficiency while at the same time electronic devices like a stereo or TV and get really hot. Is component selection and the design of an electronic device similarly a consideration when designing circuits?
After I retired I did some math and science teaching and still do occasionally for the local school district. While teaching I stressed regardless of the math or science subject how common solving the same problems becomes. This helped with the "why do I need this" kids. Does the resistor give me another example of commonality?
