9 Interview questions
Tungsten has a melting point of 3422°C (6192°F), making it the metal with the highest melting point.
Tungsten's high melting point makes it ideal for applications in high-temperature environments.
Used in light bulb filaments, where it can withstand intense heat without melting.
Essential in aerospace and military applications due to its durability and heat resistance.
Tungsten is also used in the production of hard m...
Transformers are electrical devices that transfer energy between circuits through electromagnetic induction, altering voltage levels.
Transformers consist of primary and secondary coils wound around a magnetic core.
They can step up (increase) or step down (decrease) voltage levels.
Commonly used in power distribution systems to manage voltage levels.
Example: A step-down transformer reduces high voltage from power li...
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.
When an alternating current flows through the primary coil, it creates a changing magnetic field which induces a voltage in the secondary coil.
Transformers are used to step up or step down voltage levels in elec...
The least count of a vernier caliper is the smallest measurement that can be read on the scale.
The least count is typically 0.02 mm or 0.001 inches on a vernier caliper.
It is determined by dividing the smallest division on the main scale by the total number of divisions on the vernier scale.
For example, if the main scale has divisions of 1 mm and the vernier scale has 50 divisions, the least count would be 0.02 mm...
Engine is a machine that converts energy into mechanical force. PRV controls pressure in hydraulic system. Accumulator stores hydraulic energy.
Engine is a mechanical device that converts various forms of energy into mechanical force.
PRV (Pressure Relief Valve) is used in hydraulic systems to control and limit the pressure within the system.
