Question

list the factors affecting the amount of heat producted in an element

Answer 1

The factors on which the amount of heat produced depends on the below:

1. Electric current,
2. Resistance to heating element and
3. Time period to utilise the energy.

• The material, length and thickness determines the heat production amount.
• This effect is applied on lightening appliances like filament lamps, fluorescent lamps, electric cookers, electric heaters, irons, kettles.
• Higher the resistance more the heat is produced, long the duration larger the heat is produced, more the current the heat produced is higher.
• It forms the Joule’s equation of electrical heating.

Answer 2

Answer:

Factors which affect the amount of heat produced in a heating element are:-

1. the current passed to the heating element.
2. the characteristics of the wire used in the heating element.
3. the amount of heat for with the current passes through the heating element.
