PHYS 2125 Physics Lab II_Lab-7 (LK) Series Circuit

Lab-7 (LK) Series Circuit Objective 1. Learn to build up a series circuit and a parallel circuit with three resistors and one DC source. 2. Measure current passing through each resistor, and measu re the voltage across each resistor. 3. Verify the equations of series and parallel circuits. Equipment 1 EM-8656 AD/DC Electronics Lab 2 PS-3211 Wireless voltage sensor 3 PS-3212 Wireless current sensor 4 SE-8829 Student Multimeter 5 2 Batteries 6 Wires and Resistors R R 1 R2 R3 10Ω 33Ω 100Ω Theory The relations for three resistors in series circuits are the following: R s=R1+R2+R3(1) I=I1=I2=I3(2) ∆V=∆V1+∆V2+∆V3(3) R S : Equivalent resistance of the circuit. Procedures A. Build a series circuit as shown in Figure 1 using Pasco AD/DC Electronics Lab. B. Capstone Software and checking the circuit connection. C. Data collection and calculations Using Pasco AD/DC Electronics Lab to build circuits: The names of each spring connector in the circuit board are shown in Figure 2. In the rectangular areas of Figure 2, the springs are connected in pairs, oriented perpendicular to each 1 Figure 1 This study source was downloaded by from CourseH on :59:14 GMT -05:00
