Electricity is the portion of Electricity and Magnetism dealing with the interactions involving electrostatic force, or the Coulomb force as it is often called. The Coulomb force is a force of attraction or repulsion between charged particles which can occur on stationary charges. The magnitude of the electrostatic force is inversely proportional to the square of the distance between the particles. Electricity is the only chapter to appear twice in the Main Sequence. We will revisit this material for another Main Sequence treatment again in Module 17 of the course.

Electricity is one of the two or three most important topics for the MCAT both in terms of straight-out questions on the test and because the understanding of electricity lays the groundwork for understanding chemistry. Perhaps a few other topics, such as Chemical Bonding, Solutions, or The Cell are as important for the MCAT as a direct source of questions, but if you don't understand Electricity very well, you won't understand those topics well either. Grip down and work hard here.

The WikiPremed MCAT Course is a free comprehensive course in the undergraduate level general sciences. Undergraduate level physics, chemistry, organic chemistry and biology are presented by this course as a unified whole within a spiraling curriculum.
