Introduction


An Investigation Into The

Resistance Of Conductive Putty

Primary Work

In this experiment I will be using conductive putty for the first time. I do have knowledge of electrical circuits such as parallel and series. I have knowledge of electrical equipment like bulbs, battery cells and variable resistors. And I have knowledge of the circuits’ advantages and disadvantages. My plan is to use the putty in a series circuit with an ammeter and record the currant.

Prediction

I believe that the shorter the piece of putty the stronger the currant will be. I believe this because I have found that electrons always take the shortest route.

Apparatus

In this experiment I will need; a light bulb, a

Middle

What factors could affect what happens

There are two obvious factors what come to mind and that is inaccurate measuring and uneven amount of putty. I will have to be careful with the measuring of the putty and the amount removed each time.

What I am going to change

In the experiment I am going to keep the putty’s diameter the same but change the length each time and record the amps with each reduction in the putty.

What I will measure in

I plan to measure the putties length and diameter in centimetres and the currant in amps.

What factors I am going to keep the same

In the experiment I am going to keep a

Conclusion

Method

  1. First I will set up the circuit to match the planned diagram and make sure all of the equipment is working properly. And also set the power pack to four cells.
  2. Now I will chose the largest length of putty and add it to the circuit.
  3. I will now record the reading on the ammeter and turn the power off.
  4. I will then repeat the experiment but remove a piece of putty each time and record each result.

Did anything strange happen

After the experiment I didn’t have any irregularities in the results or the experiment.

Changes to the original plan

In the experiment I used two 2 pence copper coins at each end of the putty and attached the wire to them.

Here's what a teacher thought of this essay

3 star(s)

The structure of this report is adequate but the sections lack detail.
1. There needs to be an introduction section as well as a table of results and analysis.
2. The evaluation questions lack detail.
3. There is a running commentary throughout this investigation that needs to be removed.
