A transformer works on the principle of mutual induction between two windings linked by a common magnetic flux.
Transformers consist of two inductive coils - primary and secondary windings.
When an alternating current flows through the primary winding, it creates a changing magnetic field which induces a voltage in the secondary winding.
The ratio of the number of turns in the primary winding to the number of turns in the...

Thermal insulation is necessary for proper function and basic protection.
Thermal insulation helps regulate temperature and prevent heat loss or gain.
Common types of insulation include fiberglass, foam, and cellulose.
Insulation is used in buildings, vehicles, and various industrial applications.
Examples of insulation materials include fiberglass batts, spray foam, and mineral wool.
Proper insulation improves energy effic
ECC stands for Error Correction Code, which is a method used to detect and correct errors in data transmission.
ECC is commonly used in computer memory and storage devices to ensure data integrity.
It works by adding extra bits to the data being transmitted, which can be used to detect and correct errors.
There are different types of ECC, such as Single Error Correction Double Error Detection (SECDED) and Triple Error Cor
Type B MCBs are suitable for halogen lamps.
Type B MCBs have a characteristic curve that allows for a short-term surge in current, which is common in halogen lamps.
Type C and D MCBs may trip too quickly and cause nuisance tripping.
It is important to check the wattage and voltage of the halogen lamp to ensure the correct MCB is selected.
Examples of Type B MCBs include Schneider Electric Acti 9 iK60N and ABB S 200 series.
What is the square root of 0.017?
A dead short wiring installation will have a megger reading of zero.
A dead short is a complete circuit with no resistance.
A megger is used to measure insulation resistance.
In a dead short, there is no insulation resistance to measure.
Therefore, the megger reading will be zero.
