Objective
The focus of this exercise is an examination of basic series/parallel DC circuits with resistors. A key
element is KirchhofTs voltuve law whichı states that the sum of voitage rises around a loop inust equal the
sum of the voltage drops. The voltage divider rule will also be investigated.
Theory Overview
A series circuit is defined by a single loop in which all components are arranged in daisy-chain fashion.
The current is the same at all points in the loop and may be found by dividing the total voltage source by
the total resistance. The voltage drops across any resistor may then he found by multiplying that current
by the resistor value, Consequently, the voltage drops in a scries circuit are directly proportional to the
resistance. An alternate technique to find the voltage is the voltage divider rule. This states that the
voltage across any resistor (or combination of resistors) is equal to the total voltage source times the ratio
of the resistance of interest to the total resistance.

Procedure
1.
Using the circuit of Figure 2.1 with R1 =1 k, R2 =2,2 k. R3 3.6 k, and E =9 volis, determine
the theoretical current and record it in Tahle 2.1, Construet the circuit. Set the DMM to read DC
current and insert it in the circuit at point A. Remerrber, ammeters goin-line and require the
circuit to be opened for proper measurement. The red lead should be placed closer to the positive
source terrninal. Record this current in Table 2.1. Repeat the current imeasurements at points B and
C.
2. Using the theoretical curent found in Step 1, apply Ohm's law to determine the expected voltage
drops across RI, R2, and R3. Record these values in the Theory column of Table 2.2.
3.
Set the DMM to measure DC voltage. Remember, unlike current. voltage is measured across
components. Place the DMM probes across R1 and mcasure its voltage. Again, red lead should be
placed closer to the positive source lerminal. Record this value in Table 2.2. Repeat this process for
the voltages across R2 and R3. Determine the percent deviation between theoretical and measured
for cach of the three resistor voltages and record these in the final column of Table 2.2.
