Capacitor

Capacitors: Charge stored by capacitors Q = CV in operation as a reservoir They are device that can store electric charge.It is the dielectric that separates two plates that the device.These plates have oppositely charged.The amount of charge it can store is known as capacitance.To calculate this you use : Use of capacitors as a filter in AC circuits When you use a AC supply (alternating current ).Capacitor are able to charge and discharge at a rate demanded by the speed or the flow of the supply. Units of capacitance (farad and sub-units) It is the capacitance of the capacitor ,which tells you how much of energy a capacitor can keep and it is the farad which helps you to measure it .The symbol for it is F.So, one Farad is the amount of capacitance that can store 1 Coulomb (while charged to 1 volt).However, the sub -unit are used when the unit of farad are very large for use in electronics . Sub unit Abbreviation Standard notation micro Farads µF x 10-6 nano Farads nF x 10-9 pico Farads…

The derivation of maximum power transfer theorem for purely resistive DC circuits. V_L= E x R_L/(R_L+r) P_L= 〖V_L〗^2/R_L = (E^2 〖R_L〗^2/〖(R_L+r)〗^2 )/R_L = (E^2 R_L)/〖(R_L+r)〗^2 Calculating the most favourable value of the load resistor for maximum power transfer from a DC source with a internal resistance. When any arbitrary load resistance may be selected. Let R_L= kr ( k is a positive number) P_L= kr/〖(kr+r)〗^2 E^2= k/〖(k+1)〗^2 E^2/r f = k/〖(k+1)〗^2 = 1/(k+2+k^(-1) )…

converters with reduced EMI. The principle of ZVT is that the auxiliary circuit carries a current higher than the input current flowing through the boost inductor just for a fractional part of switching time, in order to attain soft turn ON and OFF transitions of the main and auxiliary switches. So, these converters have higher ohmic losses than the simple or conventional converters that do not operate under soft transitions of switching. But the efficiency of the soft switching converters is…

3.3.3 Selection of Die Angles The split die was designed for the ease of assembly for fabrication. AISI 52100 steel was selected as the material for the die fabrication. The entry part of the die is 12 mm and has 120 mm length. The profile of the die is also shown in the solid works software. The angle of the die is 90 is maintained, the slope radius is 20 mm. the Figure.3.1 & Figure. 3.2. illustrate the split die design and solid works model of the split die. Figure. 3.1 : Split die…

METHODOLOGY To optimize the losses of given system which will simultaneously upgrade the voltage at every bus, following methodology is opted which also includes the calculation of required shunt compensation. There are two cases: Case 1: Base case The problem formed is a non linear constrained optimization problem. Interior point method is used to solve this problem. The interior-point approach to constrained minimization is to solve a sequence of approximate minimization problems. It reaches…

Dipole-dipole array has wide using in resistivity/I.P. surveys because of the low E.M. coupling between the current and potential circuits. The arrangement of the electrodes is shown in Figure( )., Electrodes c1 and c2 are separated by a distance (a), and electrodes p1 and p2 are separated by a distance (b). the distance between the potential electrodes pair c1-c2 is the same as the distance between the potential electrodes pair P1-P2 and the distance between the centers of the respective…
