Were you given the relative permittivity for each dielectric material?tsgkl said:Homework Statement
The space between the plates of a parallel plate capacitor is filled consecutively with two dielectric layers of thickness d1 and d2 respectively.If A is the area of each plate,what is the capacity of the capacitor?
Homework Equations
C=[itex]\frac{εA}{d}[/itex]
(for parallel plate capacitor with air as dielectric)
The Attempt at a Solution
i honestly don't know how to attempt this question...can anyone give me some clues...
tsgkl said:nope, relative permittivity for each material ain't given...
tsgkl said:just tell me one thing is effective thickness of dielectric 1/ε the actual thickness?
tsgkl said:as you said the effective thickness to be d1/ε1 and d2/ε2 so the answer should be εA/d1/ε1+d2/ε2
The capacity of a capacitor is a measure of its ability to store electrical charge. It is measured in units of farads (F) and is represented by the symbol C.
The capacity of a capacitor is calculated by dividing the amount of charge stored on one plate by the potential difference between the two plates. This can be represented by the equation C = Q/V, where C is the capacity in farads, Q is the charge in coulombs, and V is the potential difference in volts.
The capacity of a capacitor is affected by several factors, including the distance between the plates, the size of the plates, and the type of material used for the plates and the insulating material between them. Additionally, the potential difference applied to the capacitor and the dielectric constant of the insulating material also play a role in determining the capacity.
The maximum capacity of a capacitor is dependent on its physical properties and can vary greatly. Some capacitors have a capacity in the range of picofarads (10^-12 F), while others have capacities in the range of farads (10^12 F). However, in theory, there is no limit to the maximum capacity of a capacitor.
The capacity of a capacitor directly affects its ability to store charge and its ability to block certain frequencies of electrical signals. A higher capacity capacitor can store more charge and can therefore hold a larger amount of energy. Additionally, a higher capacity capacitor can block lower frequencies of electrical signals more effectively, making it suitable for use in filters and other electronic components.
