Question

Explain Kirchoff's law with example (for four marks question)

Answer 1

Kirchhoff's Laws for current and voltage are two principles that apply to DC circuits and networks.

The total current flowing into any DC circuit node, also called a branch point, is always the same as the total current flowing out of the node. An example is shown in the top illustration. There are four current-carrying conductors ( a , b , c , and d ) leading into the node (black dot), and two conductors ( e and f ) leading out. Direct currents in parallel add together arithmetically. Therefore, the total current flowing into the node is a + b+ c + d , and the total current flowing out is e + f . These total currents, according to Kirchhoff's First Law , must be equal.

$\textbf{Kirchoff's Law :}$


According to it the ratio of emmisive power to absorptive power corresponding to a particular wavelength and at any instant temperature is always constant called emissive power of a perfectly body at same temperature, same wavelength...
