A power system is a network of electrical components used to generate, transmit, and distribute electrical power.
Power systems consist of power plants, transformers, transmission lines, and distribution networks.
They are designed to deliver electricity from power plants to consumers.
Power systems can be categorized into three main types: generation, transmission, and distribution.
Examples of power systems include the e...
The formula for I squared R is used to calculate the power dissipated in a resistor.
I squared R is equal to the current (I) squared multiplied by the resistance (R)
It is commonly used in electrical engineering to determine the power loss in a resistor
For example, if the current flowing through a resistor is 2A and the resistance is 5 ohms, the power dissipated can be calculated as (2^2) * 5 = 20 watts
A rectifier is an electrical device that converts alternating current (AC) to direct current (DC).
Rectifiers are commonly used in power supplies to convert AC voltage to DC voltage.
They consist of diodes that allow current to flow in only one direction.
Rectifiers are used in various applications such as battery charging, electroplating, and welding.
Examples of rectifiers include half-wave rectifiers, full-wave rectifie
A transformer is an electrical device that transfers electrical energy from one circuit to another through electromagnetic induction.
Transformers are used to increase or decrease the voltage of an alternating current (AC) power supply.
They consist of two coils of wire, called the primary and secondary, wrapped around a magnetic core.
When an AC current flows through the primary coil, it creates a magnetic field that ind...

LOTO stands for Lockout/Tagout, a safety procedure used to ensure that dangerous machines are properly shut off and not started up again prior to the completion of maintenance or servicing work.
LOTO involves locking the energy isolating devices with an assigned individual lock and tag to prevent the machine from being turned on.
Types of LOTO include electrical LOTO, mechanical LOTO, and pneumatic LOTO.
Examples of LOTO ...

A transformer is a device that transfers electrical energy between two or more circuits through electromagnetic induction.
Transformers consist of two coils of wire, known as the primary and secondary coils.
The primary coil is connected to a power source, creating a magnetic field when current flows through it.
This magnetic field induces a voltage in the secondary coil, transferring energy from the primary to the second...

Transformers are electrical devices that transfer electrical energy between two or more circuits through electromagnetic induction.
Transformers are used to step up or step down voltage levels in electrical power transmission and distribution systems.
They consist of two or more coils of wire, known as windings, that are wound around a core made of magnetic material.
The primary winding is connected to the input voltage s...
