# How to change the amount of heat generated by the hotplate per unit of time if the spiral

How to change the amount of heat generated by the hotplate per unit of time if the spiral of the tile was slightly shortened after the repair?

If shortened a little, then the changes will be small. The amount of heat released when an electric current passes through a conductor is proportional to the square of the current strength, the resistance of the conductor and the time the current passes through this conductor – the Joule-Lenz law. Thus, by shortening the length of the spiral, we reduce the resistance of the entire spiral, this increases the strength of the current passing through the spiral, in turn it will begin to heat up faster, and the maximum temperature that it can gain will increase. And if you cut the spiral further, then someday it may exceed the temperature for which the environment of the spiral is designed.

One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
