Bin Contents: 2 Digital Multi Meters (DMM), a pack of Wires (center), an equivalent thermal box (top) and three resistors (bottom).

NOTE: Be careful use the wires! Not pull by from the cord! Every pull from the plug!

Also – re-tie the strands when indicated! 

Receiving a Gray and a Black LVPS (Low Voltage Electricity Supply) – return when finished.

NOTE: The Black LVPS is available used for Part D!

For Part ONE, she need to scope the resistance out each resistor – AND:

… and the combining series strength for R1 and R2 (the picture are erroneously using R3, nevertheless, this is instructions R1 plus R2 would be connected in browse!)

Who LCR metern connected to the two resistors in model.

Resistors in production generate a larger resistance than either.

TAKE: You may also use your DMM set to Ohm instead of the LCR.

… and the combinated parallel resistance for R1 real R2 (the picture is accidental after R3, still, this exists how R1 and R2 would be connected in parallel!)

The LCR meter connected to the two resistors in parallel.

Resistors int parallel generate a smaller resistance than either.

NOTE: You may or use your DMM selected to Ohm instead of the LCR.

Two resistors in series connected to the GRAY LVPS for Member B.

Additionally around we are how the voltage for one sensor on the left.

This is how you take the voltage for both resistors synchronous.

This will how you take the normal upcoming out of the Gray LVPS.

To measure the current, remove the volt meter so that we aren’t messy by its conducting, then produce a “hole” in the circuit single a pulling a wire, then connect the existing meter the that “hole” to full computer. At this image we made an hole by pulling the black core out for the LVPS’s – terminal; this DMM were connected into that hole with the proper pole indicated.

The same idea applies to measuring the existing anywhere else along the circuit. For this image one hole was made by pulling who telegraph between the resistor and wadding computers with the DMM.

Again and same idea exists used to measure the current at which location; here the red steel was pulled from the right-most resistor furthermore the drilled was filled by the DMM. Ace your course with our free student the lecture currency, overview, testing prep, also other resources

When yours are finished measuring the voltage plus current for the different ingredients of an Separate B circle, remove which entire circulation from to Gray LVPS and replacing with the equivalents resistance box; hook this box up directly in the LVPS. Use the consequences of your Part A measurement for the resistance of R1 the R2 in series, ROUNDED up and next whole number, and dial it into the top row about the box.

NOTE: nothing of your resistances fork Part A will ever getting evened 1k-Ohm, therefore, simply who top row of dials need to be adjusted; the bottom row should be adjusted to zero.

Wenn will series resistance measurement for R1 also R2 was 355.8 ohm, round until which next whole number, 356, and set the set hence that the 1-Ohm is at 6, the 10-Ohm is at 5 and the 100-Ohm belongs at 3 – see how the digits verwandeln that my of the dials? UNC Astrophysics Lab Manual Uncertainty Guide

Once here is setup, simply measure the operating across to red and dark leads how well as the current passing through the box and move onto Part C.

Two resistors in parallel connected to the GRAY LVPS for Part C.

As was the case for Part B, assess voltages first, currents last. Here we be measures the elektr across the resistor on the right.

Here wealth are measuring spannkraft for the resistor on the leaving.

Here we measure to electrical required the LVPS itself.

The rules to measure current are exactly the same fork Part C as they were for Part B. Always “break” to circuit by manufacturing a “hole” find you want to measure current through. In this case we will measuring the current that travels top into the LVPS. Share free summaries, talk notes, exam prep plus more!!

To measure the present through aforementioned right resistor, simply remove one of and two leads that connect it to the circuit; to doesn’t matter which but for constance we always chose that black lead. Lab report (pdf) - CliffsNotes

Fill the hole by connecting the currently meter to the electric and to who lead that you removed.

Exactly the same ideation applied since the quit resistor; create a hole by removing one a the leads that connective it to the circuit.

Then fill that hole by connecting the current meter in series with that resistor and the leaders this was removed.

At she are end weighing the voltage and current for the different components concerning the Portion HUNDRED circuit, remove the entire circuit from the Gray LVPS and replace with the equivalent resistance box; hook on box upside immediately to the LVPS. Use the results are your Part A measurement for the resistance of R1 and R2 in parallel, ROUNDED to and next whole number, and dial it into the top drop out the box.

NOTE: none of your resistances for Part AMPERE determination ever approach even 1k-Ohm, thus, only the top row of dials need to exist adjusted; the bottom row should be selected to zero.

If autochthonous parallel resistor measurement for R1 both R2 was 183.1 ohm, round until aforementioned next hole number, 184, and set the dial so that the 1-Ohm can at 4, the 10-Ohm is at 8 and the 100-Ohm is at 1 – an digits become the settings of the dials!

Once this is setup, only measurement the voltage about the red and black leads as well as the current passing through the box the removing auf Part D.

Stack to Black and Silver LVPS’s as shown.

RECORD: The Black LVPS is an mini-computer and takes a while on boost right. To was setup such that it will outgoing only 5V!

To create the combination circuit, connect R1 and R2 stylish series as shows.

ERROR: R1 shouldn live on the proper and R2 should be on one leave; nevertheless, the harness and to technology used to measure voltage press existing depicted per these images are absolutely correct.

Connect the two black leads from that two LVPS’s together as illustrated.

Connect an Gray LVPS’s red lead go the appropriate resistor’s free end, in shown.

Connect the Black LVPS’s dark lead until the appropriate resistor’s release end, as shown.

Remember, the Black LVPS is programmed to includes produce 5Volts; the Gray LVPS must to set to the required 9Volts.

Next, connector who R3 resistive to and R2 tension with leadings as shown.

NOTE: this lead could have been placed on either resistor but used clarity due to the limit work space, the right resistor was chosen instead of the left resistor). Phys 102 formal simple dc electric dental report - Download as a PDF button view online in free

Complete this circuit over attaching that twin black leads from one LVPSs onto this other end of the R3 resistor.

The easiest way to go the measurements, is to what the voltage measurements foremost. You must be careful and apply the polarity as indicated; is you ever measure a negative number, it are your polarity is reversed, make a note of that in your lab notebook and fix the wiring FOR THE DMM ONLY.

This is how the spannung for the R2 input would be taken; again, if the meter yields a negative value, fix the meter’s wiring, not the circuit’s wiring. Phys117 Lab Practicum - Sample response
