Principles of Electric Motor Operation Three
... The most commonly used pump control system is the pressure sensor. But no matter where in the system a pump control pressure sensor is located, there is some chance that it will be improperly activated or deactivated by sudden pressure surges. These surges do not accurately reflect the actual ...

Unit 16 Alternating Current
... Unit 16 Alternating Current Review: 7. The instantaneous voltage at any point on a sine wave is equal to the peak, or maximum, voltage times the sine of the angle of rotation. 8. The peak-to-peak voltage is the amount of voltage attained by the wave form. 9. The peak value is the maximum amount of v ...
