WebKirchhoff’s Current Law, often shortened to KCL, states that “The algebraic sum of all currents entering and exiting a node must equal zero.”. This law is used to describe how a charge enters and leaves a wire junction point or node on a wire. Armed with this information, let’s now take a look at an example of the law in practice, why ... WebApplying KCL at node B, we get the equation I1 + I2 = 0. Since we know the value of I1, we can easily determine the value of I2 as –2 A. 2. Calculate the currents I1 and I2, in the circuit below. Solution: Let us identify the two nodes in the circuit as A and B. Now applying KCL to node A, assuming the currents leaving the nodes as positive, we get fishermans spear
