Isigaba sesi-3 – Iqondwa kanjani incazelo “yamandla kagesi aphansi”

i-voltage ephansi kakhulu: i-voltage ehlinzekwa isuka emthonjeni ongaphakathi kwento kagesi engeqi ku-50 V phakathi kwamakhondakta naphakathi kwamakhondakta nomhlaba lapho into esetshenziswayo inikezwa nge-voltage elinganiselwe

I-voltage ephumayo yamabhethri ajwayelekile e-alkaline asendlini, i-voltage esebenzayo yesekethe ye-voltage ephansi ngemva kwe-transformer noma isekethe eyehlayo ye-RC ebhodini lesekethe yokulawula yezinto zikagesi ezijwayelekile zasendlini, konke okungachazwa ngokuthi amandla kagesi aphansi kakhulu. .

Njengoba kuboniswe esithombeni esingezansi, u-R1 no-C1 baqedela umsebenzi wokunciphisa ugesi, ngakho isekethe elandela u-R1 no-C1 ingachazwa njengesekhethi kagesi ephansi kakhulu.

As shown in the figure below, R1 and C1 complete a voltage reduction function, so the circuit following R1 and C1 can be defined as an extra-low voltage circuit.
