A simple potometer (figure 1) where the distance travelled by an air bubble was used to measure the rate of water uptake from the plant. Figure 1. The distance (in cm) travelled by the air bubble at a period of time (in h) was taken to be the transpiration rate for the plant....ince, the experiment was dealing with rising the temperature of the plantâs surrounding air, water in the plant will have a greater tendency to evaporate and diffuses out into the atmosphere. Transpiration rate of the plant therefore should be increasing with temperature (to a certain extent). INTRODUCTION.
A charge controller, charge regulator or battery regulator limits the rate at which electric current is added to or drawn from electric batteries.It prevents overcharging and may protect against overvoltage, which can reduce battery performance or lifespan, and may pose a safety risk. charge controller, charge regulator or battery regulator limits the rate at which electric current is added to or drawn from electric batteries.
A solar charging system is not complete without an appropriate charge controller. Most units include a charge controller to charge 12-volt lead acid batteries and inverter for drawing power.Charge controllers are also available for lithium-ion to charge 10.8V packs (3 sells in series). solar charging system is not complete without an appropriate charge controller.
