Summary of Potencial eléctrico en un punto en el espacio | Física | Khan Academy en Español

00:00:00 - 00:10:00

In this video, Khan Academy discusses the potential electric field in a point in space. They explain that the electric potential is simply an abstract number associated with points in space, and that this number is 0 at points in space with no charge, and increases as charges are placed near that point. They also explain that the electric potential field is useful for understanding how to find potential electric energy, or electric potential.

• 00:00:00 In this video, Khan Academy discusses the potential electric field in a point in space. This is one of the more confusing concepts in physics, because it sounds like energy but it's not. The electric potential is different from the electric energy, although they are related. The electric potential is simply an abstract number associated with points in space. This number is 0 at points in space with no charge, and increases as charges are placed near that point. The electric potential field around a point with a positive charge is greater than the field around a point with a negative charge. The electric potential field around a point with zero charge is infinite. The electric potential field is useful for understanding how to find potential electric energy, or electric potential. Electric potential is also known as "jules Colom", after French physicist Jules Colom. Electric potential energy is what makes things with energy useful. For example, we might use electric potential energy to obtain work or kinetic energy. The electric potential field is also interesting because it gives us a way to understand electric potential energy in any point in space based on the electric charge present. To calculate electric potential energy, we need to know the electric potential field around a point. This field is calculated by multiplying the electric potential field
• 00:05:00 This video explains the concept of potential energy, and how to calculate it using a simple formula. Potential energy is the potential energy of an object due to its position in space. In this example, potential energy is created by a positive charge. Any potential energy created by a positive charge is positive, which means that it increases the potential energy of a negative charge. This video uses a metro square as an example, and discusses how potential energy is created by the different colors' charges. Finally, the video explains how potential energy can be converted to other units such as joules or newtons.
• 00:10:00 In space, you need to be careful because sometimes people get careless and it looks like an airplane. We use voltage to measure potential electrical energy and also use it to measure voltage. Voltage is different depending on what we're measuring, but they're still related. For example, this point is at 300 jules per colom, but this point is at 100 jules per culo if I calculate the delta, it would be 200 jules per culo. This means the voltage between these two points in space is 200 volts. This is what we call the potential electrical energy between two points in space.
