It occurs when the … WebAnswer (1 of 3): A2A The area provided for the flow of magnetic flux in an air gap is larger than the cross sectional area of the core. This happens because of a phenomenon called fringing effect. This causes the real capacitance to be larger than what is being calculated theoretically. If the ...
WebOct 28, 2015 · The authors of this paper had published a two-dimensional capacitance formula for determining the capacitance of the micro-beam without etching hole [ 11 ], we can use that formula to calculate the capacitance difference of the present two test beams, that is: (8) where is the length difference of the two test beams. WebSep 24, 2024 · Fringe effect is the effect due to which the capacitance of a parallel plate capacitor is more than the capacitance calculated by the formula. It occurs when the electric field extends the area of the overlap. When we double the area of the parallel plate capacitance, the area of the overlap is also doubled.
