S Draw a power supply based on a 2x9V efficient mid-point transformer and a full-wave rectifier plus filtering. If the diodes each have a waste voltage of 0.7V, what will be the maximum voltage of the capacitor? What is the purpose of a zener diode? Give its electrical symbol. ii. B. We use two cables of length 1 = 2 m and of section s = 10 mm² to start a vehicle whose battery is discharged, linked to a battery of 12 V of a second vehicle. Calculate the available voltage for a starter of a petrol vehicle requiring 100 A and a diesel vehicle requiring 250 A. Which conclusion can you give? We give the conductivity of the copper wire y = 6.107s.m-¹. C. Remember that the concentration of free electrons in a metal with atomic mass A, density d and valence v (number of free electrons per atom) is given by the relation n = where N is the Avogadro's constant. Ndv A = 1. We consider an aluminum wire (A 27), density d = 2.7 g.cm-3, resistivity 3.44 u. cm. Calculate the concentration of free electrons (number per m³). 2. Determine the mobility of free electrons in the international system. A. i.

Answer Question 1 Subject: Renewable Energy Systems Last Digit: 15 For Solar: 1200W, 5A, 5 strings, 4 cells in each string, the cell is (60 V, 1A) And, for Wind: 800W Need calculation, figure and proper explanation. A smart home is connected to micro grid as well as utility grid. The micro grid consists of solar and wind energy. Solar power plant meet 60% of energy demand of smart home while rest is from wind power plant in normal oper- ating condition of both power plant. The smart home rated consumption power is 2000 W (Centrifugal pump, static load each 50%). 1. Design your micro grid power generation system which can meet the power consumption requirement of the smart home. Note: Solar array should contain at least two strings depending your two digit of your ID number. Please submit your IDs for getting the number of strings.
