# Calculating the Value of an Electric Field  ## Metadata - Author: [[Frank Neville H. Robinson]] - Full Title: Calculating the Value of an Electric Field - Category: #articles - Summary: The electric field produced by a charge affects other charges around it, with the strength varying based on distance and charge sign. When multiple charges are present, the total electric field at a point is found by adding the individual fields from each charge, following the superposition principle. Electric potential, measured in volts, describes the work done in moving a charge within this field and helps to understand how charges interact in space. - URL: https://www.britannica.com/science/electricity ## Highlights - In electricity the particle involved is the [electron](https://www.britannica.com/science/electron), which carries a charge designated, by convention, as negative. Thus, the various [manifestations](https://www.merriam-webster.com/dictionary/manifestations) of electricity are the result of the accumulation or [motion](https://www.britannica.com/science/motion-mechanics) of numbers of electrons.
