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 simple charger equivalent to an AC/DC wall adapter. It applies 300mA to the battery at all times, which will damage the battery if left connected too long. A battery charger, or recharger, is a device used to put energy into a secondary cell or rechargeable battery by forcing an electric current through it. The charging protocol (how much voltage or current for how long, and what to do when charging is complete, ..., for instance) depends on the size and type of the battery being charged.
