Kirchhoff’s laws

Kirchhoff’s laws are used to solve complicated electric circuits. Along with Ohm’s law, they are the first line of attack to solve any given circuit. However, bear in mind that these laws are valid only in the lumped matter discipline,

Thermodynamics: Ideal Gas

Why are gases important? The gaseous state of matter behaves differently from solids and liquids. It is neither limited in volume nor in compressibility. A gas fills entire volume of the container it is kept in, and distributes itself uniformly.
