C&S Electric Design Engineer Interview Questions and Answers

Q1. What is the difference between first angle projection and third angle projection?
Ans. 
First angle projection places the object between the observer and the projection plane, while third angle does the opposite.
• In first angle projection, the top view is below the front view.

• In third angle projection, the top view is above the front view.

• First angle is commonly used in Europe, while third angle is prevalent in the USA.

• Example: In first angle, the right side view appears on the left side of the drawing.

Q5. What is the process for creating a component drawing in AutoCAD?
Ans. 
Creating a component drawing in AutoCAD involves defining dimensions, layers, and annotations for clarity and precision.
• 1. Start by setting up the drawing environment: Choose the appropriate units (e.g., metric or imperial) and set the drawing limits.

• 2. Use layers to organize different elements of the drawing, such as dimensions, annotations, and the component itself.

• 3. Begin sketching the component using basic shapes ...read more

Q1. What are the definitions and differences between current and voltage?
Ans. 
Current is the flow of electric charge, while voltage is the potential difference that drives this flow.
• Current (I) is measured in Amperes (A) and represents the flow of electric charge.

• Voltage (V) is measured in Volts (V) and represents the potential difference between two points.

• Example: A battery provides voltage to push current through a circuit.

• Current can be thought of as the amount of water flowing through a pip...read more
