Question

We use electric appliances to transform electrical energy into more useful form of energy.1. The lamp used at home transforms the energy, state the useful form of energy

Answer 1

Explanation:

Energy transformation, also known as energy conversion, is the process of changing energy from one form to ... The energy in many of its forms may be used in natural processes, or to ...

Energy is present in many forms all around us such as electrical, kinetic, thermal, potential, and various ...

I'd speculate that light energy is most efficient from an LED bulb, sound from a piezoelectric disc, ... 1.3k views · View 1 Upvoter ... Why convert every form of energy to electricity?

However, all the energy that we put in may not come out in the desired form. For example, we put electrical energy into a bulb and the bulb produces light (which is the desired form of output from a bulb), but we also get heat from the bulb (undesired form of energy from an electric bulb).

Answer 2

Answer:

Yes, we need electrical appliances to transform electric energy into different forms .

Explanation:

We also know that :energy can neither we created nor be destroyed but can be converted from one form to another ".

All the forms of energy are useful in one or other way.

For example :

• In house we use different sources of light like tube light ,halogen light ,bulb etc .
• They all commonly falls in the category in general called as lamps .
• In lamps when we pass current , it transforms into light and heat energy.
• Not all the energy gets converted to light , part of it also gets converted to heat .That is the reason, lamps becomes hot after some time .
• The reason being, electricity produces heating effect .
• Both the forms are useful to us .Like light energy gives us light , that enable us to see even when there is no sun and heat energy keeps the temperature warm .
