• Communication...read more

Passive devices do not require an external power source, while active devices require power to function.

• Passive devices do not amplify or control the flow of electrical signals.

• Active devices can amplify, control, or generate electrical signals.

• Examples of passive devices include resistors, capacitors, and inductors.

• Examples of active devices include transistors, diodes, and integrated circuits.

A semiconductor is a material that has electrical conductivity between that of a conductor and an insulator.

• Semiconductors are used in electronic devices such as transistors, diodes, and integrated circuits.

• They have a band gap that allows them to selectively conduct electricity.

• Common examples of semiconductors include silicon, germanium, and gallium arsenide.

The process of motor manufacturing involves designing, assembling, and testing various components to create a functional motor.

• Designing: Engineers create a blueprint of the motor, specifying its dimensions, materials, and electrical requirements.

• Component manufacturing: Different parts like rotor, stator, bearings, and housing are manufactured separately.

• Assembly: The manufactured components are assembled together using specialized tools and techniques.

• Winding: Copper or alu...read more

Different types of filters include low-pass, high-pass, band-pass, and band-stop filters.

• Low-pass filters allow low-frequency signals to pass through while attenuating high-frequency signals.

• High-pass filters allow high-frequency signals to pass through while attenuating low-frequency signals.

• Band-pass filters allow a specific range of frequencies to pass through while attenuating frequencies outside that range.

• Band-stop filters, also known as notch filters, attenuate a speci...read more

Cast iron is hard and brittle, while mild steel is softer and more ductile.

• Cast iron contains 2-4% carbon, while mild steel contains less than 0.3% carbon.

• Cast iron has a higher melting point than mild steel.

• Cast iron is more resistant to wear and abrasion compared to mild steel.

• Mild steel is easier to weld and machine than cast iron.

The manufacturing process involves a series of steps to transform raw materials into finished products.

• Raw materials are sourced and inspected for quality.

• The materials are then processed and transformed through various techniques such as cutting, molding, or shaping.

• Quality control measures are implemented throughout the process to ensure the final product meets specifications.

• Assembly or integration of different components may be required.

• Testing and inspection are conducte...read more

Training procedure involves identifying training needs, designing training programs, delivering training sessions, and evaluating training effectiveness.

• Identify training needs by conducting a training needs assessment

• Design training programs based on identified needs and learning objectives

• Deliver training sessions using various methods such as lectures, workshops, simulations, etc.

• Evaluate training effectiveness through assessments, feedback, and performance metrics
