Kirchoff's voltage law
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. 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.
