Kirchhoff's Law Kirchhoff's Current Law - The basic law which states that the sum of currents flowing into any junction of an electric circuit is equal to the sum of currents flowing out of the junction.
 - where
- Ii = currents impinging on node
- Kirchhoff's Voltage Law
- The basic law which states that the sum of voltage sources around any closed circuit is equal to the sum of the individual voltage drops across the resistances of the circuit.
 - where
- Vi = potential differences around loop
Kirchhoff's Law of Radiation The emissivity of a body is equal to its absorptance at the same temperature.
Kirchhoff's First Law An incandescent solid or gas under high pressure will produce a continuous spectrum.
Kirchhoff's Second Law A low-density gas will radiate an emission-line spectrum with an underlying emission continuum.
Kirchhoff's Third Law Continuous radiation viewed through a low-density gas will produce an absorption-line spectrum.
