A) charge
B) energy
C) momentum
D) mass
Correct Answer: A
Solution :
Kirchhoff?s current law results from the conservation of charge. It applies to a junction or node in a circuit, a point in the circuit where charge has several possible paths to travel. The total charge flowing into a node must be the same as the total charge flowing out of the node. So, \[{{I}_{A}}={{I}_{B}}+{{I}_{C}}+{{I}_{D}}\] \[\Rightarrow \] \[{{I}_{B}}+{{I}_{C}}+{{I}_{D}}-{{I}_{A}}=0\] \[\Rightarrow \] \[\Sigma I=0\]
