The space between the plates of a parallel-plate capacitor is filled with a dielectric of constant
Question:
The space between the plates of a parallel-plate capacitor is filled with a dielectric of constant κρ and resistivity ρ.
(a) Show that the time constant for the decrease of charge on the plates is τ = ε0κρ
(b) If the dielectric is mica, for which κ = 5.0 and ρ = 9 × 1013 Ω · m, find the time it takes for the charge to decrease to 1/e2 ≈ 14% of its initial value.

As an online tutor with over seven years of experience and a PhD in Education, I have had the opportunity to work with a wide range of students from diverse backgrounds. My experience in education has allowed me to develop a deep understanding of how students learn and the various approaches that can be used to facilitate their learning. I believe in creating a positive and inclusive learning environment that encourages students to ask questions and engage with the material. I work closely with my students to understand their individual learning styles, strengths, and challenges to tailor my approach accordingly. I also place a strong emphasis on building strong relationships with my students, which fosters trust and creates a supportive learning environment. Overall, my goal as an online tutor is to help students achieve their academic goals and develop a lifelong love of learning. I believe that education is a transformative experience that has the power to change lives, and I am committed to helping my students realize their full potential.
