<prompt> Bheka isigaba esingezansi bese uphendula umbuzo kamuva ngolimi olufanayo nesigaba: Isigaba: Isibalo sangempela semigqa engama-525 sakhethwa njengomphumela wokulinganiselwa kobuchwepheshe obusekelwe kumashubhu we-vacuum osukwini. Ezimweni zokuqala ze-TV, i-oscillator elawulwa yi-voltage elawulwayo yayisebenza ngokuphindwe kabili imvamisa yomugqa ovundlile, futhi le frequency yahlukaniswa phansi ngenani lemigqa esetshenzisiwe kulokhu 525 ukunikeza imvamisa yenkambu 60 Hz kulokhu. Le frequency yabe isiqhathaniswa nemvamisa yomugqa wamandla we-60 Hz futhi noma yikuphi ukungafani kwalungiswa ngokulungisa imvamisa ye-oscillator eyinhloko. Ukuskena okuhlanganisiwe, kwakudingeka inombolo engafani yemigqa ngefreyimu ukuze wenze ibanga lokubuyela emuva eliqondile lilingane nezinkambu ezingafani nezingafani, okwakusho ukuthi ngisho nemvamisa ye-oscillator eyinhloko kwakudingeka ihlukaniswe phansi ngenombolo engafani. Umbuzo: Kwakunemigqa emingaki?  <response>: 525 izinkulungwane
