Proficient Automation and Controls Design Engineer Interview Questions and Answers

A diode is a semiconductor device that allows current to flow in one direction only.

• Diodes have two terminals - an anode and a cathode.

• They are commonly used in rectifiers to convert AC to DC.

• Diodes have a forward voltage drop, typically around 0.7V for silicon diodes.

• They are also used in signal processing, voltage regulation, and protection circuits.

Fixtures are devices used to hold and position workpieces during manufacturing or assembly processes.

• Jig fixtures are used to guide and control the movement of tools or workpieces.

• Clamp fixtures are used to secure workpieces in place during machining or assembly.

• Vise fixtures are used to hold workpieces firmly in position for milling or drilling operations.

• Indexing fixtures are used to rotate workpieces to specific ang...read more
