Question

Who is master about because I need help

Answer 1

Answer:

Explanation:

The capacitor can be thought of as three capacitors.C1withκ2in series withC2the onewithκ3and both are connected in parallel with capacitorC3withκ3. Note that:C1=κ1◦A/2d=κ1◦A2d,C2=κ2◦A/2d/2=κ2◦AdandC3=κ3◦Adso the total capacitance is:C=C1+C2C3C2+C3=κ1◦A2d+◦Adκ2κ3κ2+κ3=◦Ad12κ1+κ2κ3κ2+κ3Using the numerical values we get:C= 1.76×10-12F= 1.76p
