Charles law apparatus
 Product Description
Charles Law Apparatus is a scientific device used to demonstrate and study Charles's Law, which states that the volume of a gas is directly proportional to its temperature at constant pressure. The apparatus typically consists of a sealed container connected to a graduated tube or syringe, allowing measurement of gas volume changes as temperature varies. It is widely used in physics and chemistry laboratories for educational and experimental purposes, helping users understand gas behavior under thermal changes.
Whetstone bridge with pencil jockey
Product Description
The Whetstone Bridge with Pencil Jockey is a precision electrical instrument used to measure unknown electrical resistances by balancing two legs of a bridge circuit. It consists of a robust base, a wire or slide wire of known resistance, and a movable contact known as the pencil jockey to slide along the wire for accurate balancing. This apparatus is widely used in physics and electrical engineering laboratories for teaching and research purposes, helping students and technicians to understand the principles of Wheatstone bridge circuits and precise resistance measurements.
