Kirchhoff’s Laws consists of (a) Kirchhoff’s Current Law (KCL) which is based on the law of conservation of charge and (b) Kirchhoff’s Voltage Law (KVL) which is based on the law of conservation of energy.
KCL states that the algebraic sum of currents entering a node or a closed boundary is zero. Alternatively, the sum of the currents entering a node is equal to the sum of the currents leaving the node.
KVL states that the algebraic sum of all voltages around a closed path or loop is zero.
