Q2. Angke of projection explain
Ans. 
Angle of projection refers to the angle at which an object is projected or launched into the air.
• It is the angle between the horizontal line and the direction in which the object is projected.

• The angle of projection affects the range and height of the projectile.

• For maximum range, the angle of projection should be 45 degrees.

• For maximum height, the angle of projection should be 90 degrees (vertical).

Q4. Modes of heat transfer
Ans. 
Heat transfer occurs through conduction, convection, and radiation.
• Conduction: Heat transfer through direct contact between materials (e.g. touching a hot pan)

• Convection: Heat transfer through the movement of fluids or gases (e.g. boiling water)

• Radiation: Heat transfer through electromagnetic waves (e.g. feeling the warmth of the sun)

Q5. Angle of projection
Ans. 
Angle of projection refers to the angle at which an object is launched into the air.
• Angle of projection affects the range and height of the projectile.

• The optimal angle of projection for maximum range is 45 degrees.

• Different angles of projection result in different trajectories of the projectile.

• The angle of projection is measured from the horizontal axis.

Q1. HOW TO CALCULATE CT CURRENT
Ans. 
CT current can be calculated by dividing the primary current by the turns ratio of the current transformer.
• CT current = Primary current / Turns ratio

• Primary current is the current flowing through the primary conductor

• Turns ratio is the ratio of the number of turns in the primary winding to the number of turns in the secondary winding

Q4. What is TCS AND MASTER TRIP REALY
Ans. 
TCS and Master Trip Relay are protective devices used in electrical systems to prevent damage during faults.
• TCS stands for Time Current Characteristic Relay, which operates based on the relationship between time and current to trip the circuit breaker during faults.

• Master Trip Relay is a relay that receives signals from various protective relays and initiates a trip signal to disconnect the circuit in case of a fault.

Q5. WHAT IS LSC 2A AND LSC 2B
Ans. 
LSC 2A and LSC 2B are standards for lighting in commercial and industrial buildings.
• LSC 2A and LSC 2B are part of the Lighting Power Density (LPD) requirements in building codes.

• LSC 2A is for commercial buildings while LSC 2B is for industrial buildings.

• They specify the maximum allowable power consumption for lighting per unit area in a building.

• For example, LSC 2A may require a maximum LPD of 0.9 watts per square foot
