Q. Explain Kirchhoff s law and obtain necessary condition for balancing state of

wheat-Stone bridge with the help of it.​

Answer 1

$\gamma \binom{ \binom{ \binom{?}{?} }{?} }{?}$

Kirchhoff had given two laws : First law (junction theorem): The algebraic sum of all the currents meeting at a junction is always equal to zero. ... Second law (loop theorem): The algebraic sum of product of potential and currents is always equal to zero;sum of all e.m.f is equal to zero.
