Why Indian Railways use 110V AC power supply in train?

If you’re traveling on an Indian Railways train, you’ll find convenient charging sockets near your seat. These sockets provide 110V AC power, which is enough to charge most electronic devices, including laptops, tablets, and smartphones. Why not use 220V AC, which is the standard voltage for most household appliances? There are a few reasons why Indian Railways uses 110V AC instead … Read more

Wave Trap and Coupling Capacitor: Working Principle and Purpose

Wave trap, also known as line trap, are passive filters that block high-frequency signals from entering power lines. They are typically used in substation entrances and exits to protect sensitive equipment from interference and to prevent high-frequency signals from propagating onto the power grid. Working Principle Wave traps work by using a resonant circuit to … Read more

Difference Between Active & Reactive Power

Active power is the real power that does useful work in an electrical circuit. It is the power that is used to light bulbs, run motors, and power other devices. Active power is measured in watts (W). Reactive power is the power that flows back and forth between the source and load in an electrical … Read more

LVDT- Working Principle, Applications and Advantages

An LVDT, or Linear Variable Differential Transformer, is a type of transducer that converts linear displacement, the movement of an object along a straight line, into an electrical signal. This signal, typically a voltage or current, is proportional to the displacement of the object, making LVDTs highly accurate and reliable displacement measurement devices. Working Principle … Read more

Latching and Holding Current: Parameters for Thyristor Operation

Thyristors, also known as silicon-controlled rectifiers (SCRs), are crucial semiconductor devices widely used in power electronics applications due to their ability to control large amounts of current with minimal power loss. To effectively utilize thyristors, it is essential to understand the critical parameters governing their operation, including latching current and holding current. Defining Latching Current … Read more

How to calculate Power Consumption of a 1.5-Ton AC?

Air conditioners have become an essential appliance in many households, providing much-needed relief during hot and humid weather. However, their operation can also contribute significantly to household energy consumption. Understanding the power consumption of your AC unit can help you make informed decisions about its usage and potentially reduce your electricity bills. Understanding Cooling Capacity … Read more

What is a Transducer? Working Principle, Application.

A transducer is a device that converts energy from one form to another. In other words, it takes one kind of energy, like sound or light, and changes it into another kind of energy, like an electrical signal. Transducers are used in many different applications, including microphones, loudspeakers, thermometers, and pressure sensors. There are two … Read more
