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

just tell me one thing is effective thickness of dielectric 1/ε the actual thickness?

nope, relative permittivity for each material ain't given...

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...

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...

radius came out to be 10-3 m and finally potential came out to be 81V...thanks for helping guys...

Homework Statement Twenty seven charged water droplets each with a diameter of 2 mm and a charge of 10-12 C coalesce to form a single drop .Calculate the potential of the bigger drop. Homework Equations V(potential)=\frac{q}{4∏εr} The Attempt at a Solution i don't really have an...

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

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...

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"

Homework Statement is it is given in my high school textbook that a positive charge is that higher potential than negative charge? i am not able to understant it...can anyone please explain... Homework Equations The Attempt at a Solution
