Blockchain Technology

👉 Blockchain is a system of recording information in a way that makes it difficult or impossible to change, hack, or cheat the system.

👉 A blockchain is essentially a digital ledger of transactions that is duplicated and distributed across the entire network of computer systems on the blockchain.

👉 Each block in the chain contains a number of transactions, and every time a new transaction occurs on the blockchain, a record of that transaction is added to every participant’s ledger.

👉 The decentralised database managed by multiple participants is known as Distributed Ledger Technology (DLT).

👉Voltage and Current Values in Three-Phase Systems 👍👏

🔋🔌When we measure voltage and current in three-phase systems, we need to be specific as to where we’re measuring.

🔋🔌Line voltage refers to the amount of voltage measured between any two line conductors in a balanced three-phase system. With the above circuit, the line voltage is roughly 208 volts.

🔋🔌Phase voltage refers to the voltage measured across any one component (source winding or load impedance) in a balanced three-phase source or load.

🔋🚦🔌For the circuit shown above, the phase voltage is 120 volts. The terms line current and phase current follows the same logic: the former referring to the current through any one line conductor, and the latter to the current through any one component🔥

🔋👉🔌Y-connected sources and loads always have line voltages greater than phase voltages, and line currents equal to phase currents. If the Y-connected source or load is balanced, the line voltage will be equal to the phase voltage times the square root of 3.👍👏🔥🔥

A MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a type of transistor used for amplifying or switching electronic signals. It is a key component in digital and analog circuits, including microprocessors, power supplies, and motor controllers.

Structure of MOSFET

A MOSFET has three main terminals:

1. Gate (G) – Controls the flow of current.


2. Drain (D) – The output terminal where current exits.


3. Source (S) – The terminal where current enters.


4. (Substrate or Body (B) – Often connected to the source.)



The transistor operates by applying a voltage to the gate, which creates an electric field that controls the current flow between the drain and source.

Types of MOSFETs

1. Enhancement Mode MOSFET: Normally OFF; requires a gate voltage to turn ON.


2. Depletion Mode MOSFET: Normally ON; requires a gate voltage to turn OFF.



Each type can be either N-channel (NMOS) or P-channel (PMOS):

NMOS: Current flows when a positive voltage is applied to the gate.

PMOS: Current flows when a negative voltage is applied to the gate.


Applications of MOSFETs

Used in digital circuits (e.g., microprocessors, memory chips).

Power electronics (e.g., switching regulators, inverters).

RF amplifiers and analog signal processing.

Motor control and switching applications.
