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.
Charging the battery using your computer. Turn off your camcorder and connect the camcorder to a running computer using the Built-in USB Cable (). The CHG (charge) lamp turns on. The CHG (charge) lamp turns off when the battery pack is fully charged. Disconnect Built-in USB Cable from your computer. To charge the battery from a wall outlet (wall socket) using the Built-in USB Cable You can charge the battery by connecting the Built-in USB Cable to a wall outlet (wall socket) using an AC-UD10 USB charger/AC Adaptor (sold separately).
