  • Q4. How to work Air Compresor?
  • Ans. 

    An air compressor works by converting power into potential energy stored in compressed air.

    • Check the oil level and drain the water from the tank before use

    • Connect the air hose to the compressor and the tool you want to use

    • Turn on the compressor and wait for it to build pressure

    • Adjust the pressure regulator to the desired level

    • Turn off the compressor and disconnect the air hose when finished

  • Q5. What is the MIG/MAG welding machine?
  • Ans. 

    MIG/MAG welding machine is a type of welding equipment that uses a consumable wire electrode to create an electric arc for welding.

    • MIG stands for Metal Inert Gas while MAG stands for Metal Active Gas.

    • The machine uses a shielding gas to protect the weld from atmospheric contamination.

    • It is commonly used in automotive and manufacturing industries.

    • MIG/MAG welding is known for its speed and versatility.

    • The machine can be u...

  • Q6. How to calculate motor HP?
  • Ans. 

    Motor HP can be calculated using the formula: HP = (Torque x RPM) / 5252

    • Determine the torque and RPM of the motor

    • Use the formula: HP = (Torque x RPM) / 5252

    • For example, if a motor has a torque of 50 lb-ft and an RPM of 3,000, the HP would be (50 x 3000) / 5252 = 28.6 HP

  • Q7. What is the chock, Ingnetor, capacitor,?
  • Ans. 

    Chock, Ignitor, and Capacitor are electrical components used in various applications.

    • A chock is an inductor used to limit the flow of current in an electrical circuit.

    • An ignitor is a device used to ignite fuel in combustion engines or lamps.

    • A capacitor is an electrical component used to store energy in an electric field.

    • All three components are commonly used in lighting systems, power supplies, and electronic devices.

  • Answered by AI
  • Q8. How to work power factor?
  • Ans. 

    Power factor is the ratio of real power to apparent power in an AC circuit.

    • Power factor can be improved by using capacitors or inductors in the circuit.

    • A high power factor means more efficient use of electricity.

    • Low power factor can result in penalties from utility companies.

    • Power factor correction is important in industrial and commercial settings.

    • Power factor is measured on a scale of 0 to 1, with 1 being ideal.

  • Answered by AI
  • Q9. How to calculate KVARH and KVA?
  • Ans. 

    KVARH and KVA can be calculated using different formulas based on the type of circuit and load.

    • For single-phase circuits, KVA = voltage x current x power factor

    • For three-phase circuits, KVA = voltage x current x 1.732 x power factor

    • KVARH is calculated by integrating the reactive power over time

    • KVARH = (KVAR x hours of operation) / 1000

    • KVAR can be calculated using the Pythagorean theorem: KVAR = sqrt(KVA^2 - KW^2)
