地点电器名称家里学校超市路上我的感受:电视机、洗衣机、电冰箱、电饭锅、空调、饮水机······电视机、电脑、投影仪、电铃、录音机、喇叭、饮水机······电梯、空调、电视机、监控器、计价器······路灯、红绿灯、公用电话、电动车、监控器······这么东西都需要用电,电的用处可真大啊!我的小调查1799年,意大利伏特发明电堆及电池。1821年,英国人法拉第发明了电池感应现象。1866年,德国人西门子制成世界上第一台大功率发电机。1877年,爱迪生发明了电灯。风力发电电能输送的途径:发电厂→升压变压器→高压线路→降压变压器→用电单位发电厂升压变压器用电单位降压变压器高压线路xiaogan.99114.com/pifa-129/xiaogan.99114.com/pifa-133/xiaogan.99114.com/pifa-124/xiaogan.99114.com/pifa-126/xiaogan.99114.com/pifa-102/xiaogan.99114.com/pifa-127/xiaogan.99114.com/pifa-110/xiaogan.99114.com/pifa-114/xiaogan.99114.com/pifa-119/xiaogan.99114.com/pifa-130/xiaogan.99114.com/pifa-123/xiaogan.99114.com/pifa-122/xiaogan.99114.com/pifa-101/xiaogan.99114.com/pifa-105/xiaogan.99114.com/pifa-104/xiaogan.99114.com/pifa-107/xiaogan.99114.com/pifa-117/xiaogan.99114.com/pifa-115/xiaogan.99114.com/pifa-116/jingzhou.99114.com/pifa-128/jingzhou.99114.com/pifa-118/jingzhou.99114.com/pifa-125/jingzhou.99114.com/pifa-135/jingzhou.99114.com/pifa-131/jingzhou.99114.com/pifa-106/jingzhou.99114.com/pifa-136/jingzhou.99114.com/pifa-113/jingzhou.99114.com/pifa-140/jingzhou.99114.com/pifa-109/jingzhou.99114.com/pifa-103/jingzhou.99114.com/pifa-137/jingzhou.99114.com/pifa-129/jingzhou.99114.com/pifa-133/jingzhou.99114.com/pifa-124/jingzhou.99114.com/pifa-126/jingzhou.99114.com/pifa-102/jingzhou.99114.com/pifa-127/jingzhou.99114.com/pifa-110/jingzhou.99114.com/pifa-114/jingzhou.99114.com/pifa-119/jingzhou.99114.com/pifa-130/jingzhou.99114.com/pifa-123/jingzhou.99114.com/pifa-122/jingzhou.99114.com/pifa-101/jingzhou.99114.com/pifa-105/jingzhou.99114.com/pifa-104/jingzhou.99114.com/pifa-107/jingzhou.99114.com/pifa-117/jingzhou.99114.com/pifa-115/jingzhou.99114.com/pifa-116/huanggang.99114.com/pifa-128/huanggang.99114.com/pifa-118/huanggang.99114.com/pifa-125/huanggang.99114.com/pifa-135/huanggang.99114.com/pifa-131/huanggang.99114.com/pifa-106/huanggang.99114.com/pifa-136/huanggang.99114.com/pifa-113/huanggang.99114.com/pifa-140/huanggang.99114.com/pifa-109/huanggang.99114.com/pifa-103/huanggang.99114.com/pifa-137/huanggang.99114.com/pifa-129/huanggang.99114.com/pifa-133/huanggang.99114.com/pifa-124/huanggang.99114.com/pifa-126/huanggang.99114.com/pifa-102/huanggang.99114.com/pifa-127/huanggang.99114.com/pifa-110/huanggang.99114.com/pifa-114/huanggang.99114.com/pifa-119/huanggang.99114.com/pifa-130/huanggang.99114.com/pifa-123/huanggang.99114.com/pifa-122/huanggang.99114.com/pifa-101/huanggang.99114.com/pifa-105/huanggang.99114.com/pifa-104/huanggang.99114.com/pifa-107/huanggang.99114.com/pifa-117/huanggang.99114.com/pifa-115/huanggang.99114.com/pifa-116/xianning.99114.com/pifa-128/xianning.99114.com/pifa-118/xianning.99114.com/pifa-125/xianning.99114.com/pifa-135/xianning.99114.com/pifa-131/xianning.99114.com/pifa-106/xianning.99114.com/pifa-136/xianning.99114.com/pifa-113/xianning.99114.com/pifa-140/xianning.99114.com/pifa-109/xianning.99114.com/pifa-103/xianning.99114.com/pifa-137/xianning.99114.com/pifa-129/xianning.99114.com/pifa-133/xianning.99114.com/pifa-124/xianning.99114.com/pifa-126/xianning.99114.com/pifa-102/xianning.99114.com/pifa-127/xianning.99114.com/pifa-110/室內部份1不要用潮湿的手去触摸电源开关及电器用品,以免造成触电。2同一个插座不要连接太多插头使用。3在洗澡時不要触摸电器开关,因為水容易导电,所以万一漏电,很容易造成意外事故。4当你要检查或修护电器时,请先把电源切断。5家中如果有孩童,请不要让孩童将插座当成玩具或将手指头插入插座中,以免造成触电。6家庭电器和电线应该避免在潮湿的地方使用,启动电器时不要站在潮湿的地方。7插头拔起时应该把手握住插头后再把插头拔下。8电线请勿任意放置,也不要任意剪电线。室外部份1当电线漏电触及人体时,我們只能使用干燥的木棒或竹竿把电线拨开,並且迅速通知电力公司前来处理。2儿童在放风筝时,请远离电力线。3请勿用金属勾取电力线上的衣物。4天线请勿靠近电力线架设。5在任何地方发现有电线掉落,不要自行处理,要迅速通知警察单位或电力公司前来处理。1、选择节能型家电。节能型家电产品比普通家电产品能效高,其节能效果为普通家电的30%-70%。2、选用节能灯。节能型荧光灯的综合电能利用率比白炽灯高70%以上。3、合理使用空调。5、选择低谷用电。在一天中,23时到次日7时为用电低谷期。4、减少待机损耗。我国城市家庭每天待机能耗相当于一盏15瓦白炽灯24小时的用电量,一天耗电约0.36千瓦时,年耗电量131.4千瓦时。1.我们可以通过以下哪些方式获得电()A.核能B.风能C.水能D.火能ABCD2.下面有关电的发明正确的是()A.西门子发明电堆及电池B.伏特发明了电池感应现象D.法拉第制成世界上第一台大功率发电机C.爱迪生发明了电灯C3.以下哪个是电从发电厂到达我们家里的正确途径()A.发电厂→降压变压器→高压线路→升压变压器→用电单位B.发电厂→升压变压器→高压线路→降压变压器→用电单位C.用电单位→高压线路→升压变压器→降压变压器→发电厂D.升压变压器→发电厂→高压线路→降压变压器→用电单位B4、以下哪个措施是节约用电()D.选择节能型家电B.选用白炽灯A.选择高谷用电C.使用大功率电器D5.正确使用电的方法()C.同一個插座连接很多插头使用A.在检查或修护电器时,先将电源切断B.儿童在放风筝时,没有远离电力线D.插头拔起时手轻握插头后就把拔插头A
