Introduction This Instrumentation task is an independent project, aiming to demonstrate my practical, experimental and planning skills. I have the choice of three options in which to do so, and they are as follows… * Building and testing a sensor * Exploring the characteristics of a sensor * Designing and …

Aim To see what happens to the size of the shadow when certain factors are changed. Variables There are many variables in which I could change. For our experiment it will be sufficient for us only to change one variable the rest we will keep constant. Here is a list …

Introduction I wanted to find out how a rotary potentiometer could be utilized to work as a weighing scale. The specific interest is the accuracy of this method and distinguish the advantages and disadvantages of using digital readings instead of our common everyday analogue spring gauge balance at the local …

Purpose: To investigate what physical characteristics of students how it affect the power generated on running up the stairs. Hypothesis: The student that can generate the highest power would probably be Adam K, because it is so obvious that he’s the most physically fit among every one of us. In …

Aim: The aim of my investigation is to determine the specific heat capacity of aluminium. Theory: Specific heat capacity is the amount of energy required to raise the temperature of 1kg of mass by 1degree Celsius.(1) In order to calculate the specific heat capacity heat capacity (c) of aluminium I …

Introduction: Transistors are electronic devices usually used as amplifiers or oscillators in communications and computer systems. They consist of a tiny piece of semiconducting material, usually silicon or germanium, to which three or more electrical connections are made. The basic components of the transistor are similar to those of a …
