Ohm's Law

Lab Report Experiment #3 Simple DC Circuits In this experiment we learn to assemble a elementary DC rophy and measure rampart 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 gage be measured using Ohms justice. Ohms Law states that the resistance through a conductor is straightaway comparative to the voltage and inversely proportional to the current. Using this comparability we buttocks find the experimental value for resistance. Apparatus DC send out 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 higher up steps with R2. Part B 1) Connect the resistors in serial 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.
