Basics of Electric Circuits

Carga y corriente
Carga y corriente
Charge, an inherent property of matter, is responsible for a wide range of electric phenomena. The SI unit of charge is the coulomb. All matter comprises ...
Voltaje
Voltaje
The movement of electrons in a conductor requires some form of energy or work, usually provided by an external force, like a battery. This force is called ...
Potencia y energía
Potencia y energía
Energy is the total work required to drive the current through the circuit. A rise in voltage results in more work done, passing more current, resulting ...
Elementos de circuitos eléctricos
Elementos de circuitos eléctricos
Circuit elements are the basic building blocks of an electric circuit. They can be categorized as active and passive elements. Active elements can ...
Terminología del circuito
Terminología del circuito
An electrical network is a system of interconnected elements, not necessarily forming a closed path. In contrast, a circuit, also an interconnected ...
Fuentes independientes y dependientes
Fuentes independientes y dependientes
Sources in a circuit can be independent or dependent. Independent voltage or current sources supply voltage and current unaffected by other circuit ...
Ley de Ohm
Ley de Ohm
Resistors, often made from metallic alloys or carbon compounds, model a material's current-resisting behavior. Ohm's law states that the voltage ...
La ley actual de Kirchhoff
La ley actual de Kirchhoff
Kirchhoff's current law, or KCL, is based on the law of charge conservation. It states that the total current entering and leaving a node in a circuit ...
Ley de voltaje de Kirchhoff
Ley de voltaje de Kirchhoff
Kirchhoff's voltage law, or KVL, is based on the principle of energy conservation. It states that the algebraic sum of all voltages around a closed ...
Divisores de voltaje
Divisores de voltaje
In a series connection, resistors are sequentially linked, and the same current must flow through each. The voltage across these resistors can be ...
Current Dividers
Current Dividers
In a parallel connection, resistors are connected between the same pair of nodes, creating an equal voltage across each. Considering the schematic circuit ...
Resistencia equivalente
Resistencia equivalente
In circuit analysis, situations often arise where resistors are neither in series nor parallel configurations. To tackle such scenarios, three-terminal ...
Ejemplo de diseño: Pantalla táctil resistiva
Ejemplo de diseño: Pantalla táctil resistiva
A device engineer is tasked with designing a resistive touchscreen interface for a mobile device. It consists of two conductive layers: a flexible upper ...
