A bridge rectifier is a type of rectifier circuit that converts alternating current (AC) to direct current (DC) using four diodes arranged in a bridge configuration.
Consists of four diodes connected in a bridge configuration
Converts AC input into DC output
Provides full-wave rectification
Commonly used in power supplies and battery chargers
I appeared for an interview before Jun 2024, where I was asked the following questions.
Rectifiers convert AC to DC and come in various types, each with unique operational characteristics.
1. Half-Wave Rectifier: Uses one diode to allow only one half of the AC waveform, resulting in pulsating DC. Example: Simple power supply circuits.
2. Full-Wave Rectifier: Utilizes two diodes or a bridge configuration to convert both halves of the AC waveform into DC. Example: Bridge rectifier circuits.
3. Center-Tapped Fu...
MESH and NODAL analysis are techniques used in circuit analysis to determine currents and voltages in electrical networks.
MESH Analysis: Uses Kirchhoff's Voltage Law (KVL) to write equations for closed loops in a circuit.
Example: In a simple circuit with two loops, apply KVL to each loop to find unknown currents.
NODAL Analysis: Uses Kirchhoff's Current Law (KCL) to write equations at circuit nodes.
Example: In a circuit...
Logic gates are fundamental building blocks of digital circuits, performing basic logical functions based on input values.
AND Gate: Outputs true (1) only if both inputs are true. Example: A=1, B=1 -> Output=1.
OR Gate: Outputs true if at least one input is true. Example: A=0, B=1 -> Output=1.
NOT Gate: Inverts the input value. Example: A=0 -> Output=1.
NAND Gate: Outputs false only if both inputs are true. Exampl...
