They're Kirchoff's (sp?) voltage and current summing laws. They're what you use to solve basic circuit problems. The KVL says that the sum of all the voltage drops around a closed loop has to equal zero. The KCL says that the net current out of a node has to equal zero. Using one or the other form lets you write simultaneuous equations for the currents and voltages in a circuit, in order to solve for unknown currents and voltages. For example, you generally use the KCL form to solve for the transfer function of opamp circuits (where you use the simplifying assumption that the high gain of the opamp keeps its two input terminals at the same voltage via the feedback circuit).enigma said:
I thought perhaps you were just using good mentoring skills, asking rockerboi to explain in his/her own words, extent of understanding KVL and KCLenigma said:
