Experiment 5 - Kirchhoff's Voltage Law (KVL)

The second of the Kirchhoff's laws is referred to as Kirchhoff's Voltage Law (KVL) or sometimes as Kirchhoff's loop rule. It describes the relationship of the voltage in a loop of the circuit.

More generally, the rule is...    Kirchhoff's Voltage Law (KVL) In each closed loop of a circuit the voltages add up to zero. Consider the illustration of a fictitious loop. Applying the KVL gives you... U1 + U2 + U3 + U4 + U5 = 0 This is a general rule and not restricted to resistors. More on that later...

The KVL corresponds to the energy conservation law of physics.
