Answer:
The correct answer is True.
Explanation:
The feedback control system implies that to make a feedback, there must first be an error, otherwise there will be nothing to correct.
This system works so that there is an output that is controlled through a signal.
This signal will be feedback and it will signal an error which will be detected by a controller that will allow entry into the system.
In basic words, this system processes signals, samples them in the form of an output, and re-enters them feedback to detect the error signal.
Answer:
Ammeter
Explanation:
Instrument for measuring either direct or alternating electric current, in amperes. Ammeters vary in their operating principles and accuracies
Numerical weather prediction (NWP) uses mathematical models of the atmosphere and oceans to predict the weather based on current weather conditions. Though first attempted in the 1920s, it was not until the advent of computer simulation in the 1950s that numerical weather predictions produced realistic results. A number of global and regional forecast models are run in different countries worldwide, using current weather observations relayed from radiosondes, weather satellites and other observing systems as inputs.
