What is the relationship between the three voltage readings: Vi. , and VrOT? 2. Using the measurements you have made above and your knowledge of Ohm's law calculate the equivalent resistance (Ro) of the circuit for each of the three series circuits you tested. 3. Study the equivalent resistance readings for the series circuits. Devise a rule for the equivalent resistance (%) of a series circuit with two resistors? Look it up if necessary or to check. The rule: 4. Use the rule to calculate equivalent resistance (Req) of two resistors connected in series from the factory values of the resistors. Note these values in the last column of the data table. 5. For each of the three series circuits, compare the experimental results with the resistance calculated using your rule. In evaluating your results, consider the tolerance of each resistor by using the minimum and maximum values in your calculations. 6. Examine the results of Part I. What do you notice about the relationship between the three voltage readings V, , and Vror in series circuits.

Explanation / Answer

1)
V1 + V2 = Vtot

2)

V = IR

Vtot = 0.223
V1 = 0.111
V2 = 0.111
I = 0.114

Req = Vtot/I

1)
Req = 0.223/0.0114 = 20 ohms
2)
Req = 0.221/0.0055 = 43 ohms
3)
Req = 0.232/0.0031 = 66 ohms

3)

V1 = IR1
V2 = IR2
Vtot = IReq

Vtot = V1 + V2
IReq = IR1 + IR2
Req = R1 + R2

hence, below will be Req
1) Req = 20 Ohms
2) Req = 43 Ohms
3) Req = 66 Ohms

4)
1) Req = 20 Ohms
2) Req = 43 Ohms
3) Req = 66 Ohms
