Ques:- In India,we use 230V,50HZ,where as many other countries use 110V,60HZ what r d advantages and disadvantages of each of them?
Asked In :-
dover corporation, oem,
Right Answer:
**Advantages of 230V, 50Hz:**
- More efficient for power transmission over long distances.
- Allows for smaller conductor sizes, reducing material costs.
- Generally better for high-power applications.
**Disadvantages of 230V, 50Hz:**
- Higher risk of electric shock.
- Requires more robust insulation and safety measures.
**Advantages of 110V, 60Hz:**
- Lower risk of electric shock, making it safer for residential use.
- Equipment can be designed to be lighter and less robust.
**Disadvantages of 110V, 60Hz:**
- Less efficient for long-distance transmission, requiring thicker wires.
- Higher energy losses in transmission compared to higher voltages.

Ques:- Why voltge arev transformed in to 132KV/66/KV/33KV like that
Asked In :-
UOP Honeywell, rtds technologies inc.,
Right Answer:
Voltage is transformed to higher levels like 132kV, 66kV, or 33kV to reduce energy losses during transmission over long distances and to improve the efficiency of the power distribution system. Higher voltages allow for lower current, which reduces resistive losses in the transmission lines.

Ques:- How can conclude that whether it is gravity die castingcomponent or pressure die casting or low pressure diecasting and shell moulding?
Asked In :-
Right Answer:
To determine whether a component is made using gravity die casting, pressure die casting, low pressure die casting, or shell moulding, you can look for the following characteristics:
1. **Gravity Die Casting**: Typically has a rough surface finish and thicker walls, as it relies on gravity to fill the mold.
2. **Pressure Die Casting**: Features a smooth surface finish and thinner walls, as molten metal is injected into the mold under high pressure.
3. **Low Pressure Die Casting**: Similar to pressure die casting but uses lower pressure; components may have a smooth finish and are often lighter.
4. **Shell Moulding**: Usually has a very smooth surface and is made from a sand-resin mixture, often resulting in intricate designs and thinner sections.
Identifying these features will help you conclude the casting method used for the component.

Ques:- TELL ME THE STORY OF THE LAST MOVIE U SAW?
Asked In :-
Naval Group, jbm,
Right Answer:
The last movie I saw was "Dune." It follows a young man named Paul Atreides, who is the heir of a noble family. They move to the desert planet of Arrakis, which is the only source of a valuable substance called spice. As rival factions fight for control, Paul discovers his destiny and the importance of his family's legacy. The film explores themes of power, survival, and the struggle for control over resources.
