Title: Kirchhoff’s Circuit Laws Author: Doug Carlin Lab Partner: Mike Sech Date: January 18, 2000 1.0 Purpose The objective of this experiment is to study the application of Kirchhoff’s Laws to a DC circuit in which the resistive elements are in parallel and series connection. 2.0 Analysis Many DC circuits are made up of arrangements of resistors such that they cannot be broken down into a combination of resistors in series and parallel. These circuits can be analyzed by using Kirchhoff’s Laws. Kirchhoff’s Current law follows directly from the conservation of electric charge and may be stated as    N n I 1 0 for a closed loop. Kirchhoff’s Second Law follows directly from the principles of conservation of energy, and may be stated as: The algebraic sum of the emfs around a loop is equal to the algebraic sum of the potential changes around the loop. In the figure below we can see the relationship in the Kirchoff’s laws. Using the circuit and the resistor values R1=1000, R2=2000, and R3=3000 nominal ohms, the voltage drop across each resistor if the source voltage is vs= 5V The value of vs that will make I1= 5.0 mA is Using the circuit shown an equivalent resistance for R2 and R3. By combining that equivalent resistance with R1 so that there is only one resistor and one voltage supply.
