LECTURE 1: Electric Charge and Coulomb's Law

Electrostatics is the foundation of understanding electrical phenomena in biological systems, from the transmission of nerve impulses to the structure of DNA and protein folding. This lecture introduces the fundamental concept of electric charge, exploring its quantized nature, conservation principles, and the various methods by which objects acquire charge. We will develop mastery of Coulomb's Law, the cornerstone equation governing electrostatic interactions, and apply vector analysis techniques to solve complex multi-charge systems relevant to biophysical applications.

By the end of this lecture, students will be able to:

  • Understand the nature of electric charge and its properties
  • Apply methods of charging objects
  • Master Coulomb’s Law for point charges and charge distributions
  • Perform vector calculations for electrostatic forces
  • Solve complex problems involving multiple charges
