OBJECTIVES To verify experimentally the superposition
theorem
MATERIAL REQUIRED Power Supply: Low Voltage, Variable,
Regulated
Instruments: 4 DMM
Resistors (1/2W, 5%):
1 × 820 ohm
1 × 1200ohm
1 × 2200ohm
1. With power off in both power supplies and both wires S1 and
S2 in the B position, connect the circuit of Figure 2-1. Note the
polarity of the supplies carefully. 2. Turn power supply 1 on.
Adjust its voltage and S2 so that VPS1 = 15V. Set wire S1 to
position A and S2 to position B. This will apply power to R1, R2,
and R3. Measure I1, I2, I3, voltage V1 across R1, voltage V2 across
R2, and voltage V3 across R3. Record the values in Table 2-1. It is
important to note the direction of current (by using + and – signs)
as well as its value. Also note the direction of the voltage drops
V1, V2 and V3. (The voltage sign should always be opposite that of
the current sign. Thus if V1 is -, I1 will be -). Turn VPS1 off. 3.
Set S1 to position B. Adjust power supply 2 so that VPS2 = 10V. Set
S2 to position A. This will apply power to R1, R2, and R3 from
VPS2. Measure I1, I2, I3, voltage V1 across R1, voltage V2 across
R2, and voltage V3 across R3. Record the values in Table 2-2. Note
carefully the polarity of each measurement as in step 2. 4. With
VPS1 = 15V and VPS2 = 10V. Set S1 to position A (S2 should already
be in position B). Both power supplies are now feeding R1, R2, and
R3. Measure I1, I2, I3, V1, V2, and V3 as in the previous two
steps. Record the values in Table 2-3. Noting carefully the
polarity of each value. Turn the power off. 5. Using the measured
values of R1, R2, and R3 and VPS1 = 15V and VPS2 =10V, calculate
I1, I2, and I3 supplied by two sources using the superposition
theorem. Show all calculations and diagrams. Record your calculated
values in Table 2-4.
