Applications of Kirchhoff’s Law
Applications of Kirchhoff’s Law According to Kirchhoff’s law the ratio of emissive power to absorptive power is same for all surfaces at the same temperature and is equal to the emissive power of a perfectly black body at that temperature. Applications: 1) Sand is rough black, so it is a good absorber and hence in Read more about Applications of Kirchhoff’s Law[…]

Resistance
Resistance Resistance is the opposition to the passage of current within a component. The resistance of a component decides how much voltage will be dropped across it for a particular current. 1) The property of substance by virtue of which it opposes the flow of current through it, is known as the resistance. 2) Formula Read more about Resistance[…]

Phase Change
Phase Change 1) Phase: We use the term phase to describe a specific state of matter, such as solid, liquid or gas. A transition from on phase to another is called a phase change. i) For any given pressure a phase change takes place at a definite temperature, usually accompanied by absorption or emission of Read more about Phase Change[…]
Perfectly Black Body
Perfectly Black Body A body which absorbs the entire radiant heat incident upon it is called a perfectly black body. Thus, the coefficient of absorption of a perfectly black body is equal to 1. 1) A perfectly black body is that which absorbs completely the radiations of all wavelength incidents on it. 2) As a Read more about Perfectly Black Body[…]
