Kirchhoff's Rules Equipment Required: D-cell Battery AC/DC Lab Kit: Resistors, Wire Leads Digital Multimeter (DMM) PASCO Interface (for two sensors)-Xplorer GLX 1 black wire and 1 red, each with a piggy- Voltage sensor back banana plug on one end, and an alligator clip on the other end Current sensor Purpose The purpose of this experiment is experimentally demonstrating Kirchhoff's Rules for electrical circuits. Background Ohm's Law describes the relationship between current, voltage, and resistance in simple circuits. Many circuits are more complex and cannot be solved with Ohm's Law. These circuits have many power sources and branches which would make the use of Ohm's Law impractical or impossible. In 1857 the German physicist Gustav Kirchhoff developed methods to solve complex circuits. Kirchhoff produced two conclusions known today as Kirchhoff's Laws. Kirchhoff's two laws describe the unique relationship between current, voltage, and resistance in complex electrical circuits. Kirchhoff's Current Law: The current arriving at any junction point in a circuit is equal to the current leaving that junction. Stated another way: No matter how many paths into and out of a single point, all the current leaving that point must equal the current arriving at that point. This law is sometimes called the junction rule. Kirchhoff's Voltage Law: The algebraic sum of the voltages around any closed path is zero. Stated another way: The voltage drops around any closed loop must equal the applied voltages. This law is sometimes called the loop rule. Kirchhoff's Laws can be related to conservation of energy and charge if we look at a circuit with one load and source. Since the load consumes all of the power provided from the source, energy and charge are conserved. Since voltage and current can be related to energy and charge, then Kirchhoff's Laws restate the laws governing energy and charge conservation. Procedure 1. Connect the circuit shown in Figure 7.1a using any of the resistors you have 100 W (R1), 330 W (R2), 4.7 W (R3), 550 W (R.). 33 W (Rs). Use Figure 7.10 as a reference along with 7.1a as you record your data. Record the resistance values in the table below. With no current flowing (the battery disconnected), measure the total resistance of the circuit between points A and B. 2. With the circuit connected to the battery and the current flowing, measure the voltage across each of the resistors and record the values in the table below. On the circuit diagram in Figure 7.1b, indicate which side of each of the resistors is positive relative to the other end by placing a at that end
3. Now measure the current through each of the resistors Interrupt the circuit and place the DMM obtain your reading. Make sure you record each of the individual currents, as well as the current flow into or out of the main part of the circuit.IT. in series to Bridgal porotwork 1 ETH DEP LJI- Wr: R dira It Is D BEN ITH DEH CEH --- Figure 7.12 Figure 7.16 Table 7.1 smeatured Resistance.
