Kirchhoff's laws and their applications

Kirchoff's laws are applicable to

A : Kirchhoff's Current law is applicable at any junction isor node in the circuit. R : Kirchhoff's laws are general in nature .

State kirchhoff's law of blakc radiations.

In the circuit shown below, E_(1)=17V,E_(2)=21V,R_(1)=2Omega,R_(2)=3Omega and R_(3)=5Omega . Using Kirchhoff.s laws, find the currents flowing through the resistors R_(1),R_(2) and R_(3) . (Internal resistance of each of the batteries is negligible.)

Assertion : A body that is a good radiator is also a good absorber of radiation at a given wavelength. Reason : According to Kirchhoff's law the absorptivity of a body is equal to its emissivity at a given wavelength

Mention the applications of beats,

Kirchhoff's current law is the law of conservation of

State Kohlrausch's Law for the independent migration of ions. Mention the applications of the Law.

In the circuit shown in figure below, E_(1) and E_(2) are two cells having emf 2 V and 3 V respectively and negligible internal resistances. Applying Kirchhoff.s laws of electrical networks, find the values of currents I_(1) and I_(2) .
