advantages and disadvantages of heating effect of electric current
There are many advantages and disadvantages of electricity like -
1)we use Electricity tolight bulbs fan A.C etc.
1)It can make spark which in presence of gas may start a fire.
2)We can beelectrocuted if some body has bad intents and may cause severe burns which may lead to death also.etc.
I hope it gives a solution to your question.
A lot of heat is produced,which can be consequent(as a side effect which leads to wastage).Eg-microwave etc
Heat produced does work.ie intentional heat production.This principle is used to cause the filament of a bulb to glow (conversion of electric energy to heat and light energy)
1. When electric current passes through a conductor, a part of the electrical energy is converted into heat energy. This causes wastage of energy.
2. The heat produced can start fire when it becomes excessive.
Heating appliances such as toaster, a bulb,an iron etc. Use The Heating Effect of Current.
