We know that the volume of water that a plant absorbs from the soil over a period of time is nearly equal to the volume it loses by transpiration in the same duration (see Box 2). A potometer estimates the rate of transpiration indirectly by measuring the rate of uptake of water by a leafy stem.

WebNov 9, 2024 · A potentiometer is a device that measures the difference in potential between two points in a circuit. As we all know, the amount of labor involved in moving a charge from one location to another is the potential difference. When a circuit has a potential difference, current flows through the circuit. WebNov 22, 2024 · How Does a Colorimeter Work? A colorimeter’s function is based on Beer-Ambert’s Law, which postulates that the absorption and concentration of a liquid sample are directly proportional. To analyze color against an existing standard, the colorimeter sends an illuminate through a liquid sample.
