Voltage and Current Division Purpose: Apply the theory of voltage and current division. Equipment Required: 1 - HP 34401A Digital Multimeter 1 - HP E3631A Power Supply 1 - Protoboard 1 - 27 k (ohm) 1/4W Resistor 2 - 10 k (ohm) 1/4W Resistors 1 - 10 k (ohm) potentiometer Prelab: In your journal, find the voltages V 1 , V 2 and V 3 in the circuit of Fig. 1, and the currents I 1 , I 2 and I 3 in the circuit of Fig. 2. R1, 10K Ω R2, 27K R3, 10K R 1 , 10K R 2 , 27K R 3 , 10K Use a CCA (computer-aided circuit analysis) program to analyze the circuit of Fig. 1 and Fig. 2, using DC analysis. Plot the voltage across all three resistors, as the input voltage is swept from 0 to 5 V DC . Print out the circuit, analysis parameters and the graph of the results. Tape the printout(s) into your lab journal. Procedure: 1. Measure element values Measure and record the actual resistance of each resistor that will be used in constructing the circuits of Fig. 1 and Fig. 2. Label the two 10-k resistors with their values so that you can keep track of their final locations in the circuits. Measure and record the output voltage of the power supply, V S .

2. Prepare a data table Create a table similar to the one below for recording your data. Enter the data already collected into the appropriate cells. Use the measured values for the resistors and V S to compute the expected values for the voltages V 1 , V 2 and V 3 . Enter these results in the column “Actual calc’d volts.” In your lab journal draw a schematic diagram similar to Fig. 1, except label the elements with the measured resistance and computed voltage.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
