家用電器 duration 20 minutes 3 seconds 家用電器家用電器	家用電器本節目分成六個部分。 1. 電流的熱效應示範當電流通過電阻線時，電阻線會發出熱和光。當電流通過電阻線時，電能會轉換成熱能。這種現象稱為電流熱效應。金屬線的電阻越大，所產生的熱效應就越强烈。電阻大的金屬線，稱為電阻線。由於電阻線會發熱，所以又俗稱發熱線。 2. 應用電流熱效應的家用電器介紹各種日常應用電流熱效應的家用電器。包括電暖爐、風筒、電暖風機、多士爐、電熨斗和電飯煲等。 3.… 多士爐揚聲器洗衣機瓦特電功率電動機電器的功率電暖爐電流的熱效應電流的磁效應電磁鐵電鈴電風扇 electromagnet loudspeaker magnetic effect of current motor power watt doorbell electric heater heating effect of current power of electrical appliances electric fan washing machine toaster ronson@hkecl.net 0 個讚 4,546 次播放學科科學教育 Science Education 學習階段第三學習階段 (中二) Key Stage 3 (S2) 第三學習階段 (中一至中三) Key Stage 3 (S1 - S3) 作者教育局課程資源組版權聲明所有版權由香港特別行政區政府擁有上載日期 18/1/2007
