and the
theoretical values of resistance. This slight variation could have been due to
rounding off

errors
which occur when using the color codes. This method may also not work for those
who are

colorblind. This affects the accuracy of
the readings.

 

Conclusion;

To Read the First Band, You have to
know the Color-Code which we applied during the

experiment.

For the first band we have;

• Brown – 1

• Red – 2

• Green – 3

• Yellow – 4

• Green – 5

• Blue – 6

• Violet – 7

• Grey – 8

• White – 9

 

To Read the Second Band, You also
need to know the Color-Code for this band and what they

represent as done during the experiment

For our experiment we used the
color codes below;

1. Black –
0

2. Brown –
1

3. Red – 2

4. Green –
3

5. Yellow –
4

6. Green –
5

7. Blue – 6

8. Violet –
7

9. Grey – 8

10. White –
9

The Color Code for the Second Band
is Similar to the First Band.

For the third band we used the
following color codes;

1. Black –
1 ?

2. Brown –
10 ?

3. Red –
100 ?

4. Green –
1000 ?

5. Yellow –
10,000 ?

6. Green –
100,000 ?

7. Blue –
1,000,000 ?

8. Violet –
10,000,000 ?

9. Gold –
0.1 ?

10. Silver
– 0.01 ?

This is the Multiplier Value for
the Resistor.

The Following are the Color Code
for the Fourth Band of the Resistor as used for our

experiment.

1. Silver – ± 10%

2. Gold – ± 5%

3. Red – ± 2%

4. Brown – ± 1%

5. Green – ± 0.5%

6. Blue – ± 0.25%

7. Violet – ± 0.10%

8. Grey – ± 0.05%

This is The Tolerance Value for the Resistor.

 

Kirchhoff’s
Current law is as well satisfied at node D

Suggest
reason for any discrepancies in the answers;

There might
have been loose connections during the experiment.

Temperature
variations during the experiment.

The
resistance in the wire might have caused the discrepancies.

Kirchhoff’s Law

Results
Comments;

From our experiment, it is found
that the summation of currents approaching any junction is

equivalent to the sum of currents
leaving that junction.

From our experiments it has also
been shown that the summation of voltages round a closed

path or loop is zero.

 

Part 2: Kirchhoff’s Law

Conclusion;

Kirchhoff’s
Law shows that the total current or charge going into a junction has the same

value
as the charge leaving the node because it has no were else to go. ”The
algebraic sum

of all currents going
into and out of a node equals zero. This I shown in our experiment

Comments;

The theoretical and the practical
value are almost the same. The slight variation in the two

values is due to the materials used in the experiment.

 

A fully discharged capacitor behaves like short circuit,
current without voltage drop.
