State and explain Kirchhonff’s first law.​

Answer»

Answer:

Kirchhoff's current LAW (1st Law) STATES that current flowing into a node (or a junction) must be equal to current flowing out of it. This is a consequence of charge conservation.

We perform ANALYSIS on all nodes based on the inflow and outflow of current. Current DIRECTIONS at the node are based on presumed directions of the currents. As long as the assumed directions of the currents are consistent from node to node, the final result of the analysis will REFLECT the actual current directions in the circuit.
