hey
Kirchhoffs Current Law or KCL, states that the “total current or charge entering a junction or node is exactly equal to the charge leaving the node as it has no other place to go except to leave, as no charge is lost within the node“. In other words the algebraic sum of ALL the currents entering and leaving a node must be equal to zero, I
+ I = 0. This idea by Kirchhoff is commonly known as the Conservation of Charge.

Answer:
Kirchoff's Law states that the algebraic sum of currents at a junction of an electric circuit is zero. Wheatstone bridge is formed by connecting a battery B or an electric source, a plug key K and a variable resistor X between the junctions A and D and a galvanometer G between the junctions C and D
