Electronics Trivia 20

Produce coalescence metal when heated electrode is consumable and with weld pool. Uses in welding Aluminum

• Gas Metal Arc Welding (GMAW)

Produce Coalescence metal, when arc is place between stub metal.

• Stub Arc Welding

This method of monolithic IC production, elements do not penetrate the substrate. 

• Epitaxial

Used in measuring unknown capacitance.

• Capacitance Bridge

Electrodes are identified using _________ numbering system and their sizes of electrodes are from 1/16 to 5/16

• American Welding Society

The horizontal dimension displayed by the oscilloscope

• Time per Unit Division

In charging, the charging process that measures the battery voltage instead of current charge.

• Floating Current

An amplifier in which the transistor is in its active region for less than half the signal cycle

• Class C amplifier

What is the advantage of full wave bridge type transformer? 

• It uses full secondary windings

MIG welding is becoming popular in the welding industry because 

• Easy operation

An electrode similar characteristic as E6010 but it uses AC and DC currents

• E6011

PN junction at reverse bias, capacitance does not depend on this  

• frequency

Weld electrodes conduct the electric current to the two pieces of metal as they are forged together

• Resistance Weld

Person study robots

• Roboticist

During Arc welding, the current is in the range of

• 50-400A

Used in synchro system containing either differential transmitter or control transformers reduces the stator current and increases the accuracy of the system.

• Synchro Capacitor

An arc is formed between a non-consumable tungsten electrode and metal being weld

• TIG welding

Working from a product design likely to exist in a CAD data base, it compasses the computer technologies that physically produce the product including parts-program preparation, process planning, tool design, process analysis, and parts processing by numerical controlled machines

• Computer Aided Manufacturing (CAM)

The detection by robot through contact of touch, force, pattern, slip, and movement allows determination of local shape, orientation and feedback forces of a grasped workpiece.

• Tactile Sensing

The degree of which a process has been made automatic. 

• Level of Automation

Conductivities

• Silver: 108.8%
• Gold: 72.5%
• Aluminum: 63%

Absorption of slow moving electrons by intervening matter

• Ramsauer Effect

An ac bridge used for determining unknown capacitance

• Schering Bridge

Use for frequency measurement but commonly used for determining unknown capacitance with great accuracy

• Wien Bridge

Name for the very first transistor

• Point Contact

A meter w/c requires its own power source

• Ohmmeter

Serves as a cathode for dry cells

• Zinc Container

SMPS

• Switch Mode Power Supply
