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.
What's more, SLAs have different chemistry that responds differently to charging rates. The old way of charging a flooded motorcycle battery was to wire up a trickle charger (say, 1.5 or 2 Amps) for several hours, and then disconnect it when the battery acid started to bubble and boil. Yeah, but doesn't the bike charge the battery? Of course, the battery is recharged when the engine is running. And, after a ride, the battery will be at whatever voltage the bike's voltage regulator has been supplying. The important point here is that if you install a new AGM battery in an old machine that was originally designed for a flooded battery, the charging system could be working perfectly, but never keeping the AGM battery fully charged.
