Lab Report Experiment #3 Simple DC Circuits In this experiment we learn to assemble a dewy-eyed DC rophy and measure subway system using an ammeter and a voltmeter. A circuit is made using two resistors in various configurations. Readings are taken for the current at several(predicate) potencys. From the resulting readings, the resistance of the resistors may be calculated. The resistance in the circuit disregard be measured using Ohms integrity. Ohms Law states that the resistance through a conductor is straightaway relative to the voltage and inversely proportional to the current. Using this comparability we tin find the experimental value for resistance. Apparatus DC lieu supply, DC voltmeter and ammeter, two unknown resistors mounted on a box (10100 Ohms) Procedure Connect the circuit as shown in the diagram. subprogram A 1) Turn the power on and adjust the voltage to 2 volts. 2) Record the current though R1 and make foursome additional reading s with different voltages. 3) Repeat the above steps with R2. Part B 1) Connect the resistors in serial publication and make readings with at to the lowest degree(prenominal) three different voltages. Part C 1) Connect the resistors in agree and make readings with at least three different voltages. info / Analysis Part A R1| | | | | Current (mA) | potential difference (V)| rampart (Ohm)| | | | | 45.3| 2.065| 45.58| | norm granting immunity| 45.38| 68.5| 3.121| 45.56| | | | | 92.4| 4.21| 45.56| | Standard Deviation| 0.26| 111.6| 5.03| 45.07| | | | | 136.5| 6.16| 45.13| | | | | R2| | | | | Current (mA)| Voltage (V)| Resistance (Ohm)| | | | | 81.5| 2.001| 24.55| | Average Resistance| 23.43| 130.1| 3.039| 23.36| | | | | 181.3| 4.16| 22.95| | Standard Deviation| 0.66| 220.6| 5.15| 23.35| | | | | 261.5| 6.00| 22.94| | | | | Part B R1+R2| | | | | Current (mA)| Voltage (V)| Resistance (Ohm)| | | | | 33.28| 2.038| 61.24| | Average...If you want to get a full essay, ! prepare it on our website: BestEssayCheap.com
