Q. State Kirchoff's second law in electricity?
Kirchoff's second law (voltage law) the algebraic total of the products of resistance as well as current in each part of any closed circuit is equal to the algebraic sum of the emf's in that closed circuit. This law is a result of conservation of energy.
Explain the absorption and emission transitions of A and B coefficients of Einstein. Assume that N 1 and N 2 be the number of atoms per unit volume along with energy E 1 and
Flemings right hand rule: When a straight wire is moved through a magnetic field, an emf is induced in it, in the manner of the coil and magnet experiment. Once again, li
Nortan'sTheorem can be stated as follows: Any two-terminal active network having voltage source and resistances when viewed from its output terminals is equal to a constant-curren
Why do magnetic field lines contract longitudinally and exert a lateral pressure?
Each plate of a parallel plat capacitor has area 15 cm 2 and is being charged. The time rate of variation of electric field between the two plates of the capacitor is 12.6 x 10 9
