4. Experimental contents and analysis
If there are no other instructions, record the measurement up to three significant digits.
*Connect the power lines of the DMM and the DC Power Supply to the 220 v power outlet and press the power button
according to the instructions of the assistant before starting the experiment. Since all electrical and electronic equipment
consists of parts whose characteristics change with temperature, accurate measurement should be performed after
waiting for about 10 minutes after turning on the power. The power line must be connected to a 220 V power outlet |
with a ground terminal. Otherwise, it is often impossible to measure!
*Caution: Never change the voltage, current resistance measurement mode when the DMM is connected to the circuit! That is,
change the measurement mode of the DMM before connecting to the circuit or element!
* CAUTION: Always connect black lines to low voltage, or ground, and then connect black lines to
each other first, then red lines!
4.1 (Original Circuit Measurement) Construct the circuit as shown in Figure 1 and measure the voltage
applied to R. Calculate the current flowing through R, from this. Record the voltage, the current.
What is the error with the value calculated in 3.1? What is the reason for the error?
4.2 (a) Measure and record Vm using the method in Experimental Plan 3.3. That is, after setting the DMM to the
DC voltage measurement mode, remove Rt from Figure 1 and connect the DMM there to measure and record
the voltage. (b) Measure and record R Th by the method in Experimental Plan 3.3. That is, after setting the
DMM to the resistance measurement mode, remove the DC power supply from Figure 1 and connect the
position with a wire. Remove Rz and connect the DMM to the spot to measure and record the resistance. What
is the error with the value calculated in 3.2? What is the reason for the error?
4.3 Set the DMM to the resistance measurement mode, and then measure the variable resistance and adjust it to
R The. Adjust the DC power supply output voltage to VTA. Construct the Thevenin equivalent circuit and
connect R,. Set the DMM to DC voltage measurement mode, measure the voltage applied to R, calculate the
current from it, and record each. What is the error between this value and the value calculated in 3.1 and the
value measured in 4.1? Consider and determine the reference value when calculating the error.
5. Matters to be considered
The result report must be prepared in the form of a result report (example) at the front of the textbook, but be prepared by
reviewing the following
Does Thevenin's theorem work? Has the design been well practiced overall? On what
grounds do you think it went well if it went well? If it didn't work out, what do you think
is the reason? Do you think the Design Practice Plan is well prepared? Why do you think
the circuit or method you designed is wrong in the plan? What did you learn and what did
you feel? Why do you think we don't practice Norton equivalent circuits?
