KVL is derived from the fact that the voltage at any point in the circuit must have a defined value. For example, say you start at point A and travel around the loop adding up voltages along the way. If the voltage drops did not sum to zero then when you returned to point A it would have a different voltage than when you started, which is impossible.<ref name="Schwarz" />

Kirchoff's voltage law (KVL) states that that the change in potential difference (in other words, the voltage drops) in any closed electrical circuit must sum to 0.[1] A voltage drop is the change in voltage over any element in a circuit.

KVL follows from the definition of electric potential and conservation of energy.[1]
