Electric Resistance Heating Formula

Whenever an electric current flows through a material that has some resistance i e anything but a superconductor it creates heat.

Electric resistance heating formula.

The power p in watts w is equal to the voltage v in volts v times the current i in amps a. Installing electric baseboard heating is often the easiest and most effective way to add heating to a room addition or when you are converting an unheated space such as an attic or basement ideally it s always best to extend existing ductwork from your central furnace air conditioning system but sometimes it s just not possible to route additional ductwork. V v i a r ω. This article uses an older honeywell t87 type thermostat heat anticipator device to explain the relatinship between electrical resistance and heat generated by a wire when current flows through it.

The voltage v in volts v is equal to the current i in amps a times the resistance r in ohms ω. When these three conditions are merged the resulting formula is like this. What is the relationship between electrical resistance and heat generated by a wire circuit or electrical device. In formal terminology the heat corresponds to the work done by the charge.

Electric resistance heat can be supplied by centralized forced air electric furnaces or by heaters in each room. We are open service tech support parts fast lead times from 6 local plants. In the related article series we explain how adjusting the heat anticipator pointer. This resistive heating is the result of friction as created by microscopic phenomena such as retarding forces and collisions involving the charge carriers usually electrons.

Joule heating also known as resistive resistance or ohmic heating is the process by which the passage of an electric current through a conductor produces heat. The heat generated due to the flow of current is proportional to the time of current flowing when the electrical resistance and the amount of current is constant.
