A capacitor is an electronic component that stores and releases electrical energy in a circuit.
Capacitors are used to filter out noise in electronic circuits.
They can store energy and release it quickly, making them useful in timing circuits.
Capacitors are commonly used in power supplies to smooth out voltage fluctuations.
Examples of capacitors include ceramic capacitors, electrolytic capacitors, and tantalum capacitor
A resistor is an electronic component that resists the flow of electrical current, used to control the amount of current in a circuit.
Resistors are passive two-terminal electrical components
They are used to limit current, divide voltages, and adjust signal levels
Resistors are measured in ohms (Ω)
Examples include carbon film resistors, metal film resistors, and variable resistors

VCB stands for Vacuum Circuit Breaker, which is an electrical switch that uses vacuum as the dielectric medium.
VCB is used to protect electrical equipment from damage caused by overcurrents and short circuits.
It is commonly used in high voltage power systems.
VCBs are more reliable and require less maintenance compared to other types of circuit breakers.
They are also more environmentally friendly as they do not use any ...
DG stands for Diesel Generator, which is a backup power source used in case of power outages.
DG is a standalone power source that runs on diesel fuel.
It is commonly used as a backup power source in case of power outages.
DGs are often used in hospitals, data centers, and other critical facilities to ensure uninterrupted power supply.
They come in various sizes and capacities, depending on the power requirements of the fa...
DC motors convert electrical energy into mechanical energy through the interaction of magnetic fields.
DC motors have a stationary part called the stator and a rotating part called the rotor.
The stator contains the field windings that produce a magnetic field, while the rotor has the armature windings that carry the current.
The interaction of the magnetic fields causes the rotor to rotate, producing mechanical energy.
DC...
PLC stands for Programmable Logic Controller, a digital computer used for automation of electromechanical processes.
PLCs are used in industrial automation to control machinery and processes
They are programmed using ladder logic or other programming languages
PLCs can communicate with other devices and systems through various communication protocols
Examples of PLC applications include manufacturing, transportation, and b

Inrush current is the initial surge of current that flows when an electrical device is first turned on.
Inrush current occurs due to the charging of capacitive loads and magnetization of inductive loads.
Inrush current can cause voltage drops, tripping of circuit breakers, and damage to electrical components.
Inrush current can be reduced by using soft-start circuits, pre-charging capacitors, and selecting appropriate fus...
Electrical safety refers to the measures taken to prevent electrical hazards and ensure the safety of people and property.
Electrical safety involves following proper procedures for installation, maintenance, and use of electrical equipment.
It includes using appropriate protective gear, such as gloves and goggles, when working with electricity.
