IUPUI PHYS 251 LAB Page 1 of 2 KIRCHHOFF’S LAWS OBJECTIVE To calculate the currents in a multiloop circuit using Ohm’s Law and comparing the results to those calculated with Kirchhoff’s Current and Voltage Laws EQUIPMENT 3 battery packs, circuit board, 2 white shunt connectors, 3 red 75- resistive connectors, multimeter THEORY Kirchhoff’s Current Law: Σ I = 0 at any node. Kirchhoff’s Voltage Law: Σ V = 0 around any loop. Ohm’s Law: V = IR for any resistor. PROCEDURE 1) Measure the resistance of each red connector ( R 1 , R 2 , R 3 ). 2) Set up the circuit shown below. 3) Measure the terminal voltage across each battery pack ( E 1 , E 2 , E 3 ) while they are powering the circuit board. 4) Measure the voltages across the red connectors ( V 1 , V 2 , V 3 ) and calculate their currents using Ohm’s Law: I 1 = V 1 / R 1 , I 2 = V 2 / R 2 , I 3 = V 3 / R 3 . 5) Use Kirchhoff’s Laws to calculate the currents I 1 , I 2 , and I 3 using only resistances R 1 , R 2 , R 3 and terminal voltages
