Ohm’s Law Lab Investigation 10.11 (page 320)
Purpose PART 1 • We will study the relationship between VOLTAGE DROP and ELECTRIC CURRENT for ohmic resistors PART 2 • We will study the relationship between VOLTAGE DROP and ELECTRIC CURRENT for an incandescent light bulb ELECTRICAL LOAD
Construct the circuit shown on Page 320. Method Part 1 Part 2 Use the ohmic resistors as the electrical load. Use the light bulb as the electrical load. Connect resistor #1 (brown-black-brown). Take voltmeter and ammeter readings for 1, 2, 3, and 4 cells. Connect the light bulb. Take voltmeter and ammeter readings for 1, 2, 3, and 4 cells. TABLE 1 TABLE 3 Connect resistor #2 (red-red-black). Take voltmeter and ammeter readings for 1, 2, 3, and 4 cells. TABLE 2
V R I Calculations & Graphing • Calculate the Resistance • You have recorded V and I • Remember: R = V_ I • Graph Voltage (y-axis) versus Current (x-axis) of all three electrical loads on one sheet of graph paper
