Why does a wire get hot when current flows through it?
This flow is caused by the electrons within the wire being pulled by electric field As the electrons travel through the wire they collide with the atoms that make up the wire During those Often the increase in temperature is caused by an increase in current An example is a filament lamp As current increases, the filament gets hotter and the resistance of the bulb increases AOhm’s law, electric power and energy CCEA BBCOhm’s Law states that the voltage across a conductor is directly proportional to the current flowing through it, provided all physical conditions, such as temperature, remain constant As freeOhm’s law, electric power and energy CCEA Heating This increased vibration of the ions increases the temperature of the wire Energy has been transferred from the chemical energy store of the battery into the internal energy store of the wireElectric circuits Edexcel Electrical power BBC
