Isigaba sesi-3 – Iqondwa kanjani incazelo “yefrikhwensi elinganiselwe”
isilinganiso esilinganiselwe: imvamisa eyabelwe into esetshenziswa umkhiqizi. Ngokuvamile, imvamisa elinganiselwe imvamisa yokusetshenziswa okujwayelekile yezwe lemakethe eliqondiwe ngesikhathi umkhiqizo uklanywa. Njengoba emhlabeni wonke, kukhona amaza okusebenza amabili kuphela, i-50Hz kanye ne-60Hz, inani lingaba ngu-50Hz noma u-60Hz kuphela, noma womabili u-50 kanye no-60Hz. Imvamisa elinganiselwe, amandla amanje alinganiselwe noma alinganiselwe, i-voltage elinganiselwe, njll. amapharamitha ayisisekelo abonisa into…
