When you connect the wire to a battery, the battery creates an electric circuit. The electric current starts to flow through the nichrome wire. The resistance of the wire opposes the flow of the current. This opposition causes energy to be converted into heat due to a phenomenon known as Joule heating.
Joule heating occurs when the electric current passes through a conductor with resistance. The energy lost in the form of heat increases the temperature of the nichrome wire. This effect is particularly significant in nichrome wire because of its high resistance and thermal stability, making it excellent for heating applications.
In summary, the process involves an electric current flowing through a high-resistance nichrome wire, leading to the generation of heat through resistance. This heating effect makes nichrome wire suitable for various heating applications, such as resistive heating elements in toasters and space heaters.
