Passive Electronic Devices: Fundamentals and Subcomponents
Passive electronic devices serve as critical components in electrical circuits, playing a major role in shaping the behavior of signals and providing resistance to the flow of current. These devices do not require any external sources of energy to operate and typically consist of two types of components: active and passive. Active components, such as transistors and diodes, rely on the supply of energy to function, whereas passive components do not produce energy themselves but influence the distribution of existing energy within a circuit.
Some common passive electronic components include:
Resistors
A resistor opposes the flow of electric current in a circuit and is measured in ohms (Ω). Resistors can either be fixed values or adjustable, and they follow Ohm's Law, which establishes a relationship between the resistance (R), voltage (V), and current (I) in an electric circuit: V = IR.
Capacitors
A capacitor stores energy in an electric field and passes alternating current (AC) signals while blocking direct current (DC) signals. It is commonly measured in farads (F), and its capacitive reactance (XC) is given by the formula XC = 1/(2πfC), where f represents frequency.
Inductors
An inductor stores energy in a magnetic field and opposes changes in the current flow. It is measured in henries (H), and its inductive reactance (XL) is calculated using the equation XL = 2πfL, where f denotes the frequency.
Understanding the properties, characteristics, and behaviors of these passive components is essential for designers and engineers to effectively implement and optimize electronic systems, whether they involve communication, computation, or control.
Aprende sobre los dispositivos electrónicos pasivos que desempeñan un papel clave en los circuitos eléctricos al influir en el comportamiento de las señales y proporcionar resistencia al flujo de corriente.
