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. Stress strain curve in detail
Ans. 
Stress strain curve shows the relationship between stress and strain in a material under tension.
• Stress strain curve is a graphical representation of the relationship between stress (force per unit area) and strain (deformation) in a material.

• It typically consists of a linear elastic region, a yield point, a plastic deformation region, and ultimately failure.

• The slope of the curve in the elastic region is the material'...read more
