    What is the capacity of the capacitor?

    as you said the effective thickness to be d1/ε1 and d2/ε2 so the answer should be εA/d1/ε1+d2/ε2

    What is the capacity of the capacitor?

    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=\frac{εA}{d} (for parallel...

    Electric fields change in the spacing between the plates?

    Homework Statement A,B,C,D are four 'thin',similar metallic parallel plates,equally separated by distance d,and connected to a cell of potential difference(V) as shown in the attachement. Write the potentials of A,B,C,D. If B and C be connected by a wire,then what will be the potentials...

    Explaining Positive Charge Higher Potential than Negative Charge

    so this will mean +16v will be greater than -18v even though magnitude wise 18 is greater than 16...

    Explaining Positive Charge Higher Potential than Negative Charge

    calculating the work done in bringing a unit positive charge from infinity to that point in a region of electrostatic field will mean deriving formula formula for electrostatic potential due to a point charge... so you mean to say what dreamlord said that is replace q with -q in the...

    Explaining Positive Charge Higher Potential than Negative Charge

    well the definition says,"electrostatic potential at any point in a region of electrostatic field is the minimum work done in carrying a unit positive charge(without acceleration) from infinity to that point"
