What is rectifier circuit?

A rectifier circuit is an electronic circuit that converts alternating current (AC) into direct current (DC). It typically consists of diodes arranged in a specific configuration to allow current flow in only one direction, effectively converting the AC input into a pulsating DC output. Rectifier circuits are fundamental in power supplies and various electronic devices … Read more

Why do we use a resistor in an RC circuit?

Resistors are commonly used in RC (resistor-capacitor) circuits for various reasons that depend on the specific application and circuit design. One primary purpose of using a resistor in an RC circuit is to limit the charging and discharging currents of the capacitor. In circuits where capacitors need to charge and discharge smoothly without excessive current … Read more

Why do we use a relay instead of a switch ?

Relays are often preferred over manual switches in electrical circuits for several reasons, primarily due to their ability to handle higher currents and voltages safely and reliably. Unlike manual switches that are manually operated to open or close a circuit, relays are electromechanical devices that use an electromagnetic coil to control the switching of contacts. … Read more

How do inductive transducers function ?

Inductive transducers operate based on the principle of electromagnetic induction, where changes in a physical quantity (such as displacement, pressure, or position) cause corresponding changes in inductance. Here’s how they function in various applications: Inductive transducers work by utilizing a coil or multiple coils wound around a core material. When the physical quantity being measured … Read more

Why is a diode non ohmic a circuit ?

A diode is considered non-ohmic in a circuit because its current-voltage relationship is nonlinear. Unlike ohmic devices such as resistors, which follow Ohm’s law (where current is directly proportional to voltage), a diode exhibits a different behavior. Specifically, a diode allows current to flow in one direction (forward biased) with very little resistance once a … Read more
