Br.CAT International ITI Electrician Interview Questions, Process, and Tips

Q1. What is poroosity
Ans. 
Porosity is the measure of empty spaces in a material, often used in geology and engineering.
• Porosity is the ratio of void spaces to total volume in a material.

• It is expressed as a percentage.

• Porosity is important in fields like geology for assessing rock formations and in engineering for determining the strength of materials.

• Examples of porous materials include sponges, pumice stones, and aerogels.

Q2. What is permeability
Ans. 
Permeability is the property of a material that allows fluids or gases to pass through it.
• Permeability is a measure of how easily a substance can pass through a material.

• It is often used in geology to describe how easily fluids can flow through rocks or soil.

• Permeability can be affected by factors such as pore size, connectivity, and fluid viscosity.

• Materials like sandstone have high permeability, while materials like

Q1. What is ohm's law
Ans. 
Ohm's law states that the current flowing through a conductor is directly proportional to the voltage applied across it, and inversely proportional to the resistance of the conductor.
• Ohm's law is represented by the formula V = I * R, where V is voltage, I is current, and R is resistance.

• It helps in calculating the current, voltage, or resistance in a circuit when the other two values are known.

• For example, if a circuit...read more

Q1. What is current 3 phase voltage
Ans. 
Current is the flow of electric charge. 3 phase voltage refers to the voltage in a three-phase power supply system.
• Current is measured in amperes (A)

• 3 phase voltage is typically 208V, 240V, 480V, or 600V

• In a three-phase system, there are three voltage sources that are 120 degrees out of phase with each other

• The voltage between any two phases is called line voltage, while the voltage between any phase and neutral is cal

Q2. 3 phase voltage= 440
Ans. 
440V is the standard voltage for 3-phase power supply.
• 440V is the root mean square (RMS) voltage of the three alternating currents in a 3-phase power supply.

• It is commonly used in industrial and commercial applications.

• The voltage may vary depending on the country's electrical standards and regulations.
