Lab Report On Ohm 's Law

(b) Due to the fact that R1 and R2 are identical, what would you guess is the voltage across each resistor is individually? Why?

The control experiment for this investigation will be the experimental setup of 5 trials using 5oC as the temperature. All the steps in the method will be followed.

In this lab we will be studying electric field plotting through the use of various apparatus. The equipment we will be using includes a digital voltmeter, voltage probes, carbonized acetate sheets, battery, and other tools of measurement. The goal of the lab is for us is to be able to plot lines for charge distributions and to create electric field lines by providing an electric current through carbonized sheets. Once we have completed constructing the electric field lines for the plate charge distribution, we will continue to calculate for the electric field (E = Vx) and begin to plot for the dipole charge distribution. When we have collected all the data needed, we then will finish calculating for all the remaining variables and complete the rest of the lab report.

If you have not already read the laboratory description for part 1 in the ELEC 2531 Lab 3 report document, do so before proceeding.

The programmed algorithm is shown in Figure 6.The program was developed using LabVIEW System design software. The entire experimental set-up is shown in Figure 7.

As this voltage and current was very low it resulted in a low power value which then had the contradiction of resulting in a low fill factor. The maximum power value was found to be quite large

However, this was not the case. Discrepancies occurred between the two sets of values due to experimental errors. Some of the sources of error during the experiment include: drift on the voltmeter that affected the accuracy of measurements (instrumental error), rounding-off errors during calculations and the old resistance box. However, these errors can be eliminated by using a new functional resistance box, recording readings at right angles, and using four decimals in calculations to avoid rounding off errors.

The most profound finding of this experiment is that the inductance of the secondary coil does not influence the overall performance of the system in a real-world scenario. The factor that influenced the real-world performance most is the total resistance/loss in the secondary, which is shown by an inversely proportional relationship. As the effective resistance of the secondary coil decreased, its performance went up, as shown by the trend lines in Graphs 1 and 4.

3) In the lower left of the screen is a meter for indicating electric potential, in volts, created by the charge that you introduced. Record the voltage and turn on “Plot”.

\emph{Testing Strategy:} The graph between applied load in the range 0.5 grams to 575.5 grams and change in voltage is plotted. The graph obtained (see Figure~\ref{f:olggraph}) shows the inconsistent readings at many points for different combination of force applied. Also, the best curve equation is close to cubic, which is indication of bad design.\\*

4) Use the tape measure to find and record the distance from the charge to the equipotential sensor. 2.03 m

The variables been shown in the simulater are the voltage, current, and ressistance. V(volts) = I(Ampers)* R(Ohms).

1. Using the information provided in the Introduction and your observations from Part 1, hypothesize as to the type of electrolyte the following solutions would be. Justify the hypothesis from a chemical standpoint.

voltage of +5 Volts and -5 Volts. Following are the pre-setting which need to be done

Throughout this research paper, the reader will have a better understanding of the different forms of resistance. Also the reader will have the ability to compare the two types of resistance which were active and passive. And finally the reader will be abl
