What Does A Resistor Do And Why Is It Important?

WebbExplanation: For a given field current, control of series field is achieved by means of a diverter, a low resistance connected in parallel to series winding. A more practical way of a series field control is changing the number of turns of the winding by suitable tappings which are brought out for control purpose. WebbA surge arrester is a kind of protective device used to limit voltage on equipment by bypassing or discharging surge current. It helps to prevent continued flow, directs them to the ground, and is capable of repeating this process. Surge arresters don’t stop lightning or absorb them. It diverts the lightning and limits the voltage.

WebbA tap changer is a device fitted to power transformers for regulation of the output voltage to required levels. On-load tap-changers (OLTCs) are indispensable in regulating power transformers used in electrical energy networks and industrial applications. Webb9 jan. 2015 · The main reason it's hard to measure resistance changes is that the Arduino (and most IC) contain a tiny system called Analog to Digital Converter (ADC). This system translates changes in analog voltage to a series of 1's and 0's that can be in turn converted to an Integer for example.
