Q2. What is mean by optical fibre, why colour are used for fibre
Ans. 
Optical fibre is a thin, flexible, transparent fibre that transmits light signals over long distances.
• Optical fibre is made of glass or plastic and is used for high-speed data transmission.

• The colour of the fibre is used to identify different types of fibres and to indicate the direction of the light signal.

• Single-mode fibres are usually yellow, while multimode fibres are usually orange or aqua.

Q1. How u create 3 modeling in design sofware
Ans. 
To create 3D models in design software, use tools like extrude, revolve, and loft.
• Start by creating a 2D sketch of the object you want to model

• Use the extrude tool to give the sketch depth and create a 3D object

• Use the revolve tool to create a 3D object by rotating a 2D sketch around an axis

• Use the loft tool to create a 3D object by blending two or more shapes together

• Combine these tools to create complex 3D models

Q3. For critical jobs which which angle of projection is important
Ans. 
The angle of projection that is important for critical jobs is the isometric projection.
• Isometric projection is important for critical jobs as it provides a three-dimensional view of the object.

• It allows for accurate measurements and analysis of the object's dimensions and angles.

• Other types of projections, such as orthographic projection, may not provide enough detail for critical jobs.

• For example, in engineering, iso...read more

Q1. What do you mean by electrical electric current
Ans. 
Electric current is the flow of electric charge in a conductor.
• Electric current is the rate of flow of electric charge.

• It is measured in units of amperes (A).

• Electric current can be either direct current (DC) or alternating current (AC).

• DC flows in one direction while AC periodically changes direction.

• Examples of electric current include the flow of electrons in a wire and the movement of ions in an electrolyte solutio
