You can also calculate the potential as the work done by the external force in moving a unit positive charge from infinity to that point without acceleration. Created by Mahesh Shenoy.

A positive charge, Q , is located at point O . The electrostatic force due to Q , slowly pulls a point charge (no acceleration), q = 1.5 C , from point B to point A , doing 3 J of work. What is the potential …

We can't imagine our lives without electricity. But what exactly is electricity? How does electricity light up our houses? What does a battery do? What is the cost of electricity? We will answer all these …

The units of electric potential are joules per coulomb, hinting at its connection to energy. The video explains how to calculate electric potential and its relationship with voltage.

And in case that's confusing, remember that the definition of electric potential is the amount of electric potential energy per charge. So to just put a number in here so it's not so abstract, let's say V two …

Explore the distinction between electric potential energy and electric potential, often confused terms in electrostatics. Understand how electric potential, or voltage, is associated with position, while electric …

Learn how potential energy is stored in systems of objects that interact through gravitational, electric, or magnetic fields. Discover how changing the arrangement of objects in a system affects the system's …

Review the key terms and skills related to Kirchhoff's loop rule, including how to determine the electric potential difference across a component.

Key points: A resting (non-signaling) neuron has a voltage across its membrane called the resting membrane potential, or simply the resting potential. The resting potential is determined by …
