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.
The compact unit is loaded with features, including long battery leads and power cord, charge indicator, self-resetting circuit breaker and a auto trickle charge mode after your battery is fully charged.
