Sources Of Error Circuit Lab


For trial 2, the 10 Ω resistor has the same range and the 51 Ω resistor has a range of 48.45 Ω to 53.55 Ω. Once these values were measured using the appropriate instrumentation the resistance in the circuit was computed using Ohm's Law. V1, V2, and VTOT are all about equal.

Stay logged in Physics Forums - The Fusion of Science and Community Forums > Science Education > Homework and Coursework Questions > Introductory Physics Homework > Menu Forums Featured Threads Recent What do you notice about the relationship between the three voltage readings V1, V2, and VTOT in parallel circuits? Using the measurements you have made above and your knowledge of Ohm’s law, calculate the equivalent resistance (Req) of the circuit for each of the three series circuits you tested. No, create an account now.

Possible Sources Of Error In Ohm's Law Experiment

If you're not allowed to do that, make sure the connection surfaces are free from dirt and tarnish. While there is some discrepancy in the accepted and calculated values this can be reasonably explained by the presence of random error in the experiment. Please try the request again.

The specifications probably include zero offset, reading accuracy, and impedance. Although these differences may appear a little high a deeper analysis of the numbers rejects this notion. This required knowledge of the formulas for series and parallel circuits to understand why different values for "R", "I", and "V" were obtained in spite of the fact that the physical Sources Of Error In Physics You can only upload a photo (png, jpg, jpeg) or a video (3gp, 3gpp, mp4, mov, avi, mpg, mpeg, rm).

Series And Parallel Circuits Lab Sources Of Error Although the resistance of each is not supposed to affect the circuit, the presence of the milliammeter and voltmeter cannot be discounted. Part 4: Cosmic Acoustics Struggles with the Continuum – Part 7 Frames of Reference: A Skateboarder’s View Spectral Standard Model and String Compactifications Ohm’s Law Mellow Digital Camera Buyer’s Guide: Tripods Email Adam.

The comparison of the resistance of the eureka wire and the parallel resistance of eureka wire and the voltmeter indicates how major this error would be. Sources Of Error In Measurement I am retired now. If you did the former, then you probably picked up some error from that.

Series And Parallel Circuits Lab Sources Of Error

Log in Sign up Home Florida Institute of Tech PHY PHY 1002 physics 2 lab 10_1 Possible sources of error in this lab include random SCHOOL Florida Institute of Tech COURSE Part 3: 7. Possible Sources Of Error In Ohm's Law Experiment Answer Questions A heat engine has a cold reservoir of 250°C and a hot reservoir of 715°C. Sources Of Error In Experiments When looking for sources of error in an experiment, one good thing to do is to look for simplifying assumptions in your theory.

Labeled Diagrams See attached sheet. useful reference For each of the three series circuits, compare the experimental results with the resistance calculated using the rule for calculating equivalent resistance outlined in the Theory section. The accepted total resistance of the parallel circuit is 83.3 ohms. Paul J. Types Of Sources Of Error

What did you discover about the current flow in a series circuit in Part 3? You can only upload files of type 3GP, 3GPP, MP4, MOV, AVI, MPG, MPEG, or RM. Newer Than: Search this thread only Search this forum only Display results as threads More... http://phabletkeyboards.com/sources-of/sources-of-error-in-series-circuit.php Conclusion During part 1 of the experiment….procedure (what was done), results, expectations and sources of error.

In addition, a DC voltmeter and a DC ammeter must be used properly in order to correctly measure the current and voltage present in the two circuits that are to be Examples Of Experimental Errors Trending I'll try again. Our Privacy Policy has details and opt-out info.

Yes No Sorry, something has gone wrong.

The calculated values using Ohm's Law and the formula for parallel circuits, in which the total resistance of resistors in parallel is equal to the reciprocal of the sum of the This will decrease the current flowing because the current has to fight its way through this additional resistance. Course Hero is not sponsored or endorsed by any college or university. Sources Of Error Measuring Resistance What is the efficiency of the engine?

Sources of Error in a Physics Experiment? You want this additional resistance to be insignificant compared to the rheostat.

You can only upload a photo or a video. Sign up to view the full content. This may be attributed to the fact that the single measurement of the current read for the series circuit was in error more than the current readings taken for the parallel The electromagnetic spectrum does not contain Radio waves and microwaves Light waves Sound waves Gamma waves?

Once again, taking into account all the possible sources of error and uncertainty, this experiment, in which resistance was calculated based on measurements of current and voltage obtained using a milliammeter Using the two measured quantities of current and voltage, the resistance of the circuits can be calculated by applying Ohm's Law. Concepts: Current Electricity Ohms Law Series Circuits Parallel Circuits However, there are other sources of error that may have contributed to the 8.6 % error. Fluid fills the container shown in the figure.

ExperienceI have a BS in Physics and an MS in Electrical Engineering. This would have more affect when you decreased the setting of the rheostat. If the two measured currents in your parallel circuit were not the same, which resistor had the large current going through it?

This lab also helped us to better understand how the resistor, inductor and capacitor work together in the circuit and also notice the importance and effect of resonance frequency in such This gives a theoretical Req range of 19.0 Ω to 21.0 Ω for trial 1. Or did you take a voltmeter and actually measure the potential difference across the terminals? Individually R1 has an accepted value of 125 ohms and R2 has an accepted value of 250 ohms; however, using experimental data R1 was calculated to be 111.4 ohms and R2
