Presentation transcript:

 a German physicist  fields of study are electrical circuits, spectroscopy, and the emission of black-body radiation by heated objects  discovered cesium and rubidium with Robert Bunsen

 Also called Kirchhoff’s current rule  The sum of currents entering a junction equals the sum of currents leaving the junction.  I in =  I out  Based on conservation of charge.

Junction – a point where three or more branches are connected. Junctio n

 Also called Kirchhoff’s voltage rule  The sum of voltage around a closed loop is equal to zero.  V = 0  Based on conservation of energy.

Loop – a closed path in the circuit.
