Abstract: Researchers were continuously working towards trade-off solutions to know the relationship between charge, voltage and current with time during charging and discharging of capacitor. But knowing the characteristics of charge, voltage and current during charging and discharging of capacitor using smaller values of capacitor is becoming increasingly challenging. The main objective of this paper is to investigate the behavior of voltage, current and charge during charging and discharging of capacitor by using smaller values of capacitors. In this paper the behavior of voltage, current and charge during charging and discharging capacitor was investigated experimentally. The experiment was done by using Electrolytic capacitor (100µF) and resistor (1MΩ). The graph was plotted by using origin soft ware. As the experimental result shows that, during charging capacitor at (t = 0) the voltage and charge are zero, and it increase exponentially with time. But current decrease exponentially. Whereas during discharging capacitor at (t = 0) the voltage and charge are maximum, it decreases exponentially with time. But current decrease exponentially. This shows that the experimental result match’s with theoretical result. This work will support science students and researchers to know the detail knowledge about the relationship about voltage, current and charge with time even if the capacitor value is small.

Abstract: In Chad, the lack of drinking water is a real problem in the desert area. This paper focuses on the statistical assessment of water production using a wind source in North-Eastern Chad to serve the population. The statistical analysis method used for estimating wind power density is the Weibull distribution. Two sites were chosen for the study, namely Fada and Amdjarass. The data used is collected over eight years and two statistical tests were used to assess the convergence of the different distributions. Average wind speeds were calculated to assess the energy potential of the sites. At 10m from the ground, the average wind speeds obtained over eight (08) years are 6.11 m/s at Amdjarass with predominant winds from the North East and 5.43 m/s at Fada with predominant winds from the East. This makes the two localities with high wind potential in Chad. An electric water pumping technique was used for water quantity estimation by testing four (04) wind turbines. The GEVMP aerogenerator meets the needs of both sites. Installed on a 55m high mast, this two-blade aerogenerator can provide on average between 3778.3 m3 of water/day to 1511.3 m3 of water/day for a system ranging from 60m to 150m in head at Fada. This corresponds on average to 139.36l/d/pers (60m HMT) to 55.74l/d/pers (150m HMT). As in Amdjarass, the GEVMP aerogenerator can provide between 3986.3 m3 of water/day to 1594.5 m3 of water/day for a system ranging from 60m to 150m in head. This corresponds on average to 129.57l/d/pers (60m HMT) to 51.82l/d/pers (150m HMT).
