ECE 22 Power Voltage Current and Resistance Measurement Lab Report An experiment in Circuit Analysis that needed to be done using Multisim to answer all the questions in the experiment manual. Please find the attached file. Notes on Experiment #4
Use only Ohm’s Law, Voltage Division, Current Division and the Power equation to do
your circuit analysis.
Do part I as is.
In part II you will be measuring and recording the voltages with both the DMM and the
scope. So set up your data tables accordingly.
For the circuit analysis in part I you MUST USE VOLTAGE DIVISION to find every
voltage value. For the voltage Vi across a single resistor Ri we have:
Vi = [Ri/(R1 + R2 + R3 +R4)]*Vs
If you need the voltage across two adjacent resistors, say R1 and R2, then let
Ri = R1 + R2 in the above formula and you have it!
For the circuit analysis in part III you MUST USE CURRENT DIVISION to find every
current value. In this case you MUST find Is first.
Is = Vs*(1/R1 + 1/R2 + 1/R3 + 1/R4) = Vs/Req, Where Req = R1||R2||R3||R4
Then for the current Ii in a single resistor Ri we have:
Ii = [Gi/(G1 + G2 + G3 + G4)]*Is, Where G = 1/R (conductance)
For the current in two resistors, say R1 and R2, then Gi = G1 + G2

ECE 225 Experiment #4
Power, Voltage, Current, and Resistance Measurement
Purpose:
To measure V, I, and R with a Digital Multimeter (DMM) and the V with the
oscilloscope; verify voltage and current division rules; investigate the effect
of power dissipated by a resistor
Equipment: Keysight DSO-X 2012A Oscilloscope, Keysight 34461A Digital Multimeter
(DMM), Keysight 33500B Function Generator, Keysight U8031A Triple
Output DC Power Supply, Universal Breadbox
I.
Power
Accurately measure the resistance of a 27-ohm, 1/4 watt resistor. If the error is
more than 5%, ask your lab instructor for a replacement. Calculate the DC voltage
which results in 1/2 watt of power dissipation in the resistor, and set the DC
supply to that value. Use the + and – terminals of the Output1. Set the current
limit to 200 mA. Attach cables from breadboard directly to the + and – terminals
of the DC voltage supply. Use hookup wire to connect the resistor to the cables.
Wait a few minutes and feel the resistor. Comment. Disconnect the resistor from
the DC supply and measure the resistor’s value quickly and see if the value has
changed as a result of the abuse. Now repeat the experiment with the DC supply
set for a power dissipation of 1 watt (four times the rated amount). Don’t burn
yourself! Be sure to measure the resistor again before you start the 1 watt trial.
II.
Voltage Division
For the next two parts you will need accurate values of the resistors in order to
verify the voltage division and current division shortcuts. Measure these values
accurately if you have not already done so. Set up the circuit in Figure 1 using the
DC supply as VS. Set VS to 10 volts. Then by measuring V1, V2, V3, V4, V12, V123,
and VS with the DMM, verify the voltage division rule for each of these voltages.
Present your results (measured values vs. values calculated on the basis of the
voltage division rule, using the accurately measured R values) in the form of a
table. Next, replace the DC supply with the function generator, set it for a
waveform 4sin(4000pit) volts (be sure the DC offset is zero), and repeat.
Next, repeat all of the above measuring the voltages with the oscilloscope. Use
the differential technique of measurement.

R1 = 1.0K
R2 = 3.3K
R3 = 2.0K

III.
Current Division
Verify the current division rule, in a manner similar to your verification of the
voltage division rule above, for the circuit in Figure 2. Let VS be 10 volts DC.
Measure the currents using the DMM. You do not need to use the scope. The
scope is a voltmeter.
NOTE: WE WILL NOT DO AC CURRENT MEASUREMENT. THE AC
CURRENTS ARE TOO SMALL TO BE MEASURED BY THE DMM IN
THIS LAB.

R2 = 3.3K
