Depending on the controlled variable and how fast or slow it changes, every control system must have a controller that provides a signal to the final control element. Keep in mind that the controller is the decision maker that sends a signal to a final...
Thyristors are semiconductors that are, essentially control systems for switching and controlling power. The ones used most are Silicon-Controlled Rectifiers (SCRs), Diode AC Switches (Diacs), Triode AC Switches (Triacs), and Uni-Junction Transistors (UJTs). Here's a breakdown of each one and how they function: ...
What is the importance of using P&ID for process engineering? I currently work at Georgia Pacific in wood products, we make OSB. I have worked as an electrician on shift for several years which meant that there were several...
Abstract A brief description of the experiment. The abstract should not exceed four or five sentences. Introduction In your own words, explain the reason for performing the experiment and give a concise summary of the theory involved, including any mathematical detail relevant to later...
What are some of the effects that power quality might play in the selection of different devices? For example, power supplies may be subject to transients, harmonics, variations in voltage and (sometimes) frequency and so forth. Also, what about temperature variations, vibration, dust, and other...
What is Structured Query Language (SQL)? Describe the syntax of a query. What is the purpose of the WHERE clause in a query? Can you write a query without using the WHERE clause? Explain. ...
Janet is revising the website for her office at work. She wants to add a contact and feedback form to the contact page of the website. She thinks the form will bring invaluable feedback and afford users an additional method to contact the office. What...
Thyristors are semiconductor devices that are used as switches to control higher-level voltages and current. Unlike variable control, thyristors have two states: fully open or fully closed. In your original post, answer the following: Discuss the operation of different thyristors such...
Find an example of "back to the drawing board" due to design failure or the need to improve a design. Summarize the issues you found. Hello, This might be one of the most “back to the drawing board” inventions there...
Discuss the difference between latches and flip-flops: The biggest difference I took away from latches vs. flip-flops, is that a latch does NOT have a clock signal, but a flip flop will always have a clock signal. Another difference between the two is that...
