Example Formula

The magnitude of the electric field (E) produced by a uniformly charged sheet is given by the following equation:

E = σ / (2 × ε0)
  1. E: This represents the electric field.
  2. σ: This is the surface charge density (amount of charge per unit area) on the sheet.
  3. ε0: This is the permittivity of free space, which is a constant with a value of approximately 8.85 × 10-12 C2/N m2.

Who wrote/refined the formula

This concept can be traced back to the works of 19th-century physicists such as Michael Faraday and James Clerk Maxwell, who made fundamental contributions to the understanding of electromagnetic fields. The formula itself is a direct application of Gauss's Law, part of Maxwell's equations, to a specific geometry.

Real Life Application

The concept of the electric field of a charge sheet is particularly applicable in the field of electronics. Many electronic devices and systems, such as capacitors and metal-oxide-semiconductor field-effect transistors (MOSFETs), operate based on the principles of charge accumulation and electric fields.

Key individuals in the discipline

James Clerk Maxwell and Michael Faraday are notable figures in this discipline. Faraday's experiments in electromagnetism paved the way for Maxwell to formulate his groundbreaking equations that describe electromagnetic phenomena, including the electric field of a charge sheet.

Interesting Facts

  1. The electric field of a uniformly charged infinite plane sheet is constant and does not decrease with distance, which is counter-intuitive and interesting.
  2. This concept is critical in the design of modern electronic devices, including capacitors and semiconductors, that have dramatically transformed our way of life.
  3. Understanding electric fields has led to groundbreaking technologies like the MRI scanner, which uses electromagnetic fields to generate detailed images of the human body.


The study of the electric field of a charge sheet is a fascinating and essential part of physics, particularly electrodynamics. It serves as a cornerstone in understanding more complex electromagnetic phenomena and has immense practical applications, from the design of electronic components to breakthroughs in medical imaging. The ongoing exploration of electric fields continues to open new frontiers in our understanding of the physical world and the development of cutting-edge technologies.
