  • Q1. How to calculate motor fl current
  • Ans. 

    Motor full load current can be calculated using the formula: FLA = (P x 746) / (V x Eff x PF x 1.73)

    • Calculate the power (P) of the motor in horsepower

    • Determine the voltage (V) of the motor

    • Find the efficiency (Eff) of the motor

    • Identify the power factor (PF) of the motor

    • Use the formula FLA = (P x 746) / (V x Eff x PF x 1.73) to calculate the full load current

  • Q2. What is ammeter how it is working
  • Ans. 

    An ammeter is a device used to measure electric current flowing through a circuit.

    • Ammeters are connected in series with the circuit in which the current is to be measured.

    • They have a low resistance to prevent significant voltage drop in the circuit.

    • Ammeters are calibrated in units of amperes (A) or milliamperes (mA).

    • They typically have a needle or digital display to indicate the current reading.

    • Ammeters can be analog o

  • Q1. How does a diesel genrator work?
  • Ans. 

    A diesel generator works by converting diesel fuel into mechanical energy which is then converted into electrical energy.

    • Diesel fuel is injected into the combustion chamber where it ignites and creates high pressure gases that push the piston down, creating mechanical energy.

    • The mechanical energy is then converted into electrical energy through the use of an alternator.

    • The alternator uses a magnetic field and a conduct...
