In 1845, a German
physicist, Gustav Kirchhoff developed a pair or set of rules or laws which deal
with the conservation of current and energy within Electrical Circuits.
KIRCHHOFF’S CURRENT LAW
This law 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(exiting) + I(entering) = 0.
