Measurement of the Electric Fields in Parallel Plate Capacitors.

This article explores the measurement of electric fields in parallel plate capacitors. It explains the concept of parallel plate capacitors and their applications in experiments related to electric charges. The article acknowledges that real-life capacitors do not meet ideal conditions and presents standard formulas for ideal capacitors. It also discusses a simple experiment using a charged bead to measure the electric field inside and outside a parallel plate capacitor, along with the theoretical framework and equations involved. The authors conducted experiments to measure the electric field in both regions and discovered the presence of a field outside the capacitor due to the fringing effect. The study provides a theoretical explanation and a practical apparatus for measuring the electric field of a parallel plate capacitor. The article was authored by Taehun Jang, Hyejin Ha, Sang Ho Sohn, and Jungmin Moon, with Sang Ho Sohn being a professor of physics at Kyungpook National University in South Korea.
