OBJECTIVES: state the relationship among current, resistance, and voltage differentiate series and parallel circuit compute the total resistance of series and parallel circuit 5 6 7 Kirchhoff's Law 12 quantify how current flows through a circuit and how voltage varies around a loop in a circuit. Kirchhoff's current law (1st Law) states that the current flowing into a node (or a junction) must be equal to the current flowing out of it. This is a consequence of charge conservation. Kirchhoff's voltage law (2nd Law) states that in any complete loop within a circuit, the sum of all voltages across components which supply electrical energy (such as cells or generators) must equal the sum of all voltages across the other components in the same loop. This law is a consequence of both charge conservation and the conservation of energy. Calculate the total resistance in the circuit 14 Calculate the total resistance in the circuit Calculate the total resistance in the circuit
