Watch the video and see how data is typically collected. Write down the values presented in the video. The first column is volts (volts) and the second column is current (Amps). Note that the current will be presented in mill-amps. Convert that to amps. The spreadsheet is provided but going through the video and studying how the circuit is constructed is always a bonus.
Plot current vs. voltage. Label the graph. Is it linear?
Perform a LINEST. Note: The slope should be LaTeX: frac{1}{R}1 R. Note the slope and the uncertainty. Compare with the measured value (multimeter) of R. [R = 97.8 LaTeX: pm± 0.1 LaTeX: OmegaΩ]
Answer the following:
a. From your results, did your conductor (resistor component) obey Ohm’s Law?
b. Did you compare reasonably with the actual value of R?
b. Explain the proper conditions for utilizing am ammeter in this experiment. What properties does it have and how was it placed in the circuit?
The post Proper conditions for utilizing am ammeter first appeared on COMPLIANT PAPERS.
