Potenciálval

Potenciálval, also known as potential difference or voltage, is a fundamental concept in physics and electrical engineering. It refers to the difference in electric potential between two points in a circuit. This difference drives the flow of electric current, which is the movement of electric charge. The unit of measurement for potential difference is the volt (V), named after Alessandro Volta, the inventor of the voltaic pile.

Potential difference is a scalar quantity, meaning it has magnitude but no direction. It is often represented by the symbol ΔV or V, and can be calculated using the formula ΔV = V2 - V1, where V2 and V1 are the potentials at two different points in the circuit.

In a simple circuit, potential difference is created by a power source, such as a battery or a generator. This difference in potential causes electrons to flow from the point of higher potential to the point of lower potential, creating an electric current. The potential difference is what allows electrical devices to function, as it provides the energy needed to perform work.

Potential difference is also a key concept in understanding other electrical phenomena, such as resistance, capacitance, and inductance. It is a crucial factor in the design and analysis of electrical circuits, and is essential for understanding the behavior of electrical systems.
