Finding the Spring Constant of a Copper Spring Using a Potential Divider 1.0 Aim To undertake an experiment to assess the behaviour of a potential divider as a sensor. 2.0 Objectives * Build and test a sensor. * Explore the characteristics of the sensor. * Calibrate the sensor. 3.0 Introduction The system, which I am using to find the constant of a spring, could be used for quality control in industries where springs are made. Potential dividers are used in strain gauges in buildings to calibrate subsides. The potential divider in the circuit is going to be used as a position sensor. A potential divider is simply two resistors, across which a voltage is applied, with the output being taken from the junction of the resistors. If a single variable resistor is used for R1 and R2, then the output voltage can be varied, and this is the basis of the volume control. 4.0 Method A...
