IS 2720 Part 8 is a standard for determining the water content of soil by oven drying method.

• IS 2720 Part 8 is a standard method used in geotechnical engineering to determine the water content of soil samples.

• The method involves weighing a soil sample, drying it in an oven, and then re-weighing to calculate the water content.

• The water content is calculated as the difference in weight before and after drying, divided by...read more

The maximum on BOCW & site situation refers to the highest number of workers allowed on a construction site based on safety regulations.

• BOCW stands for Building and Other Construction Workers, regulations set limits on the number of workers allowed on site

• Site situation includes factors like space, hazards, and emergency evacuation plans

• Maximum number of workers should be determined based on safety assessments and comp

Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

• Ohm's law is represented by the equation I = V/R, where I is the current, V is the voltage, and R is the resistance.

• It is named after Georg Simon Ohm, a German physicist who first formulated this law.

• This law is applicable to all types of circuits, including DC and AC circuits.

• It is use...read more

DOL starter stands for Direct-On-Line starter, used to start motors by directly connecting them to the power supply.

• DOL starter is the simplest and most common type of motor starter.

• It directly connects the motor to the power supply without any intermediate starting method.

• It provides full voltage to the motor during starting, which can cause high inrush current.

• DOL starters are suitable for small to medium-sized motor...read more

APFC PANEL stands for Automatic Power Factor Correction Panel, used to maintain power factor in electrical systems.

• APFC PANEL automatically monitors and corrects the power factor of electrical systems.
