Indian Herb Specialties Interview Questions and Answers

A transformer is a static device that uses mutual induction to convert voltage levels.

• Transformers are used to increase or decrease the voltage in electrical circuits.

• They consist of two or more coils of wire, known as windings, that are wound around a core.

• The primary winding is connected to the input voltage source, while the secondary winding is connected to the load.

• When an alternating current flows through the primary winding, it creates a changing magnetic field in the ...read more

Silica gel is a desiccant that absorbs moisture to keep things dry.

• Silica gel is a porous, granular form of silicon dioxide.

• It is commonly used in packaging to prevent moisture damage to products.

• It can also be found in humidifiers, dehumidifiers, and air conditioning systems.

• Silica gel changes color as it absorbs moisture, indicating when it needs to be replaced.

• It is non-toxic and safe to handle.

X-mer oil is a type of cooling oil used in transformers to dissipate heat generated by the coil.

• X-mer oil is a mineral oil with high dielectric strength and thermal conductivity.

• It is used to cool the transformer coil and prevent overheating.

• The oil also acts as an insulator to prevent electrical breakdown.

• X-mer oil is typically tested for purity and quality to ensure proper functioning of the transformer.

• Examples of X-mer oil include Shell Diala, Cargill FR3, and ABB Envirot...read more

Critical path is the longest sequence of tasks in a project that must be completed on time in order for the project to finish on schedule.

• Critical path determines the shortest possible duration for a project.

• It helps in identifying which tasks are most crucial for the project timeline.

• Any delay in tasks on the critical path will directly impact the project's completion date.

• Activities on the critical path have zero float or slack.

• Example: In a construction project, laying the...read more

Total float is the amount of time a schedule activity can be delayed without delaying the project completion date.

• Total float is calculated by subtracting the early start date of an activity from its late start date.

• Activities with total float can be delayed without affecting the project's critical path.

• Total float is also known as slack or float.

• It helps in identifying activities that have flexibility in their start and finish dates.
