| THE CIRCUITS - KIRCHHOFF'S CURRENT LAW (KCL) | ||
Kirchhoff’s Current Law (KCL) states, in essence, that the signed sum of all currents entering a node equals the signed sum of all currents leaving a node. By stating it this way, the algebraic sum of all currents at a node is zero. For example, a three-path node has currents entering of 2 and 3 amps. The current leaving must be 5 amps, as no other path is available and the electrons cannot be accumulated in the node. In other words, all KCL essentially states is that what goes in, must come out! |
