【二種電工】極性確認|白線をWに挿す本当の理由
第二種電気工事士の極性確認を「丸暗記なし」で本質から解説。コンセントのW端子に白線をつなぐのは電気の帰り道(大地への安全経路)を物理的に確定するためです。 ▼ この動画で学べること ・極性あり器具(コンセント)と極性なし器具(片切スイッチ)の違いと理由 ・アナログテスターが交流を測れる仕組み(内蔵整流器)と抵抗計が電池から電流を流す理由 ・パイロットランプ3機能(常時点灯・同時点滅・異時点滅)が同じ単線図になる理由 ・ZCT(零相変流器)がベクトル合成ゼロの崩れで地絡を検知する仕組み ・埋込連用取付枠の中央配置が「物理的なストレス分散」のためである理由 ▼ 参考ソース ・https://eleking.net/k22/k22k/k22k-pol... ・https://eleking.net/k22/k22k/k22k-pil... ・https://denginoheya.com/encyclopedia/... ・https://hegtel.com/tesuta.html ・https://denken-trainer-zekizap.com/de... #第二種電気工事士 #電気工事士 #電工二種 #極性確認 #電気資格 #電気工事
