2. PROGRESS
Performing the Experiment: In this part, summarize the experimental steps for each section in the
order they actually happened, and show circuits diagram.
Example
Part 1 :
First we determined the resistors value via multimeter measurments and then we constructed the
circuit using the resistors (serial or paralell) shown in Figure 1. Then multimeter was connected to
the circuit in series, we measured the current through each resistor. The multimeter was connected
to the circuit in parallel, we measured the voltage across each resistors with the multimeter and we
filled in Table 2.

3. CONCLUSION
In this part, give some comments on the lab with your own words and write what you have learned
about the experiment.
Example :
In conclusion, we have seen that the algebraic sum of the currents at nodes A, B and C is zero. Also
the loop equation for the loops I-II and III satisfied Kirchoff’s voltage law. So the Kirchoff’s
current and voltage laws have been experimentaly verified.
Although the sum of the currents at node A is zero, the sum was found as -0.01 A, because of the
tolerance of the resistors and reading errors from the multimeter.
Sum of the powers of all elements in the circuit was found almost equal to zero in the experiment
whereas it should have been zero theoretically.
4. POST LAB
In this part, answer all post lab questions. Present details as much as you can. Elaborate your
answers. Type written-reports must be submitted. Hand-written reports are absolutely not accepted.
Also use an appropriate software program such as MICROSOFT EXCEL, MICROSOFT VISIO,
MATLAB to plot the graph, draw the circuit and write the formulas.
