Resistor Heating Up at Keith Maxey blog

Resistor Heating Up. When resistors get too hot two things can happen: The electric field within the resistor structure accelerates (does work on) the electrons increasing their kinetic energy however, this. This increase in current sees an increase in electrons which start to bump and rub into each other causing friction resulting in energy released as heat. I use a 5v battery that can supply up to 2a, a 10 ohm resistor and a 5v 500 ma led. A 1 watt resistor can safely dissipate 1 watt, and will not catch fire or do other nasty things. Exceeding a resistor’s power rating causes more current to flow through the resistor. However, this does not mean that at 1/2. Damage is caused to the resistor internally and externally. Current is 21.5 ma and this will cause a power of 4.63 watts in the 10k resistor. I would recommend a 10 watts resistor. The important resistor for heating up is the 10k resistor. Theoretically the resistor limits the current to. Fixed resistors with a fixed resistance level can see this level start to fluctuate when excess levels of heat pass through the resistor. Every resistor has to dissipate power given by the formula ixixr or vxv/r regardless of the power rating of the resistor. This is the main reason resistors get hot.
