In this lab, we will investigate Ohm's Law, and study how resistors behave in various combinations. Along the way, you will establish that certain measurements are a ected by the way in which circuit elements are connected to each other.
In this experiment, the current flowing through a resis-tor will be measured as the voltage across the resistor is varied. From the graph of this data, the resistance is determined for Ohmic resistors (Ri, i = 1, 2, 3). Non-Ohmic resistors (R4, light bulb) do not obey Ohm’s Law.
2. Experiment procedure: 1- Choose randomly three different resistors. 2- Read the resisters value by using resistor colour code method. 3- Using the multimeter, read the resistors value (Measured value). 4- Write down all the measured and calculated values on the table below. Deviation = |)(R measured – R nominal)/ R nominal( | × 100% Table 1
Plan your experiment to determine the equivalent resistance for series or parallel configurations. Create a data tables in your lab notebook. Conduct the experiment and record all the data you take for series and parallel configurations.
EXPERIMENT 9: OHM’S LAW Introduction: In this lab, you will use a variable power supply to subject a resistor (of known resistance) to a variety of voltages. Your objective will be to test Ohm’s Law, which asserts that the resulting current through the resistor (as well as the rest of the circuit) is proportional to the applied voltage.
Introduction: This experiment is designed to investigate the relationship between current and potential difference in series and parallel resistor circuits using the ideas of conservation of energy and charge.
To use the DMM you need to know how to set it to make the desired measurement (function), and how to set it for best accuracy (range). The purpose of this lab exercise is to learn how to measure resistance with the DMM. An error analysis will compare the measured resistor values to the labeled resistor values using a spreadsheet.
Place twenty given resistors on your breadboard. Make sure that there is only one resistor per row and that each leg of the resistor is in a separate row. See figure below for proper resistor placement. 2. Write down the resistor band colors for each of the resistors in the table. 3. Using the color codes determine the components theoretical ...
Use a multimeter (if available) to measure the resistance of resistors R2, R3, & R4 on the circuit board. Enter the values in Table II. Theory Resistance: Using Equivalent Circuits and the values for the resistors from Table II, calculate the equivalent resistance for each of the three circuits shown on the previous page.
