What is the relationship between the size of the electric current passing through a length of wire and its heating effect?

The relationship is that as the current passing through the wire increases so does the heating effect in the wire. To see its effect just use the formula:
W=I2R
R is resistance in ohms
I is current in amps
W is the heat output in watts
Hope this helps

What effect of current is utilised in bulb?
Heating effect of electric current.
Introduction of heating effect of electric current and electric heater fuse metals used for thermocouple?
Can heat energy be converted to light energy and how?
Is the heating element on a stove a chemical reaction?
No. It is a physical process cause be passing an electric current through a wire.
Which effect of current does the fuse wire in electric circuits utilize?
The heating effect is used. Normally the current flows through the fuse without undue heating. But if too much current passes through, the fuse will heat and melt, thus stopping the current which could cause a fire if it was not stopped.
What are 3 essentials aspect of electric current?
An electric current has three 'effects'. These are (1) heating effect, (2) chemical effect, and (3) magnetic effect.Any one of these effects can be used to define the unit of measurement for electric current, the ampere.Until around 1947, for example, the 'chemical effect' was used -i.e. the ampere was based on the mass of silver deposited on an electrode during electrolysis.Since then, the 'magnetic effect' has been used -i.e. the ampere is based on the force between two current-carrying conductors, due to their surrounding magnetic fields.
Who found heating effect of electric current?

What does electric current do for us?
If the question means "What does electricity do for us?" then we could mention lighting, heating, cookers, refrigerators, telephones and cellphones, radios, TVs, computers for a simple start. If the question seeks to differentiate between electric voltage and electric current, then voltage is the measure of the energy of an electric charge and current is a measure of the flow of the charge.
What is the relationship between the size of an electric current passing through a lenght of wire and its heating effect?
The higher the current, the more heat generated. Also, the smaller the diameter of the wire, the higher the heat. It is important to choose the correct amperage rating of the wire to prevent fires.Another AnswerThe work done by an electric current is the product of the square of that current, and the resistance of the conductor. The resulting heat depends upon the difference between the temperature of the conductor and that of the surrounding air. Remember, heat is defined as the transfer of energy between objects at different temperatures.
What are the advantage and disadvantages of heating effect of current?
Disadvantages of the heating effect of electric currents are: short circuits, house fires, and explosions. Advantages of the heating effect of electric currents are: electric light, toasting food, and keeping a room warm.
Practical application of heating effects of electric current?

Why does the cord of an electric heater not glow while the heating element does?
The heating element of an electric heater is a "resistor", the cord which conducts the electricity is not. The resistance of the element of an electric heater is very high. As current flows through the heating element, it becomes red hot and glows. On the other hand, the resistance of the cord is low. It does not become red hot when current flows through it.
