Electrical Experiment Pdf Unlike fixed resistors, which maintain a constant resistance value, variable resistors allow manual or automatic adjustment, making them indispensable in applications requiring tuning, calibration, or real time control. Many common sensors are actually variable resistors—they dynamically change their resistance in response to some human or environmental input. for example, thermistors change their resistance based on temperature, photocells based on light, force sensitive resistors (fsrs) based on force.
Experiment 5 Temperature Dependence Of Different Resistors And This document summarizes an electrical engineering lab experiment on variable resistors. the objectives were to measure resistance using a rheostat, introduce potentiometers, and determine maximum power output. Another variable resistor is the ldr, the light dependent resistor, sometimes called photoresistors. ldrs are electronic components that change their resistance in response to changes in the intensity of light falling on their surface.
