Ex. 135

We calculate the current(with the multimeter) and resistance (R= V/I)

V              I(A)            R

0. 0                    0. 0                     0. 0

0. 5                    0. 8                     0. 63

1. 0                    0. 10                 10. 00

1. 5                    0. 12                 12. 50

2. 0                    0. 14                 14. 29

2. 5                    0. 16                 15. 63

3. 0                    0. 18                 16. 67

3. 5                    0. 19                 18. 42

ex 134

We create a mixed circuit, later with the digital multi-meter we calculate the voltage

Vsource(V):4.5
VB1      (V):1.7
VB2      (V):1,1
VB3      (V):1,7

Ex. 133

We create a parallel circuit and with the digital multi-meter we calculate the voltage 

Vsource (V) 4.5
VB1       (V) 1.65
VB2       (V)1.35
VB1       (V)1.5

ex. 132

We create a serie circuit and with the digital multi-meter we calculate the voltage.

Vsource (V) : 3.9
V B1     (V) : 1.35
VB2      (V) : 1.3
VB3     (V) : 1.21

Parallel and series circuit

Parallel Circuit :  Circuit with more than one path for electron to travel

Series Circuit : Circuit with only one path for electrons to travel
