第五节家庭用电
精选练习
考点一、家庭电路的组成
1.（2018•山西）将经常开关的电灯，带保险盒的插座和接冰箱的三孔插座正确的接入图的电路中。
【答案】如图所示
【解析】根据开关只准接在火线上，螺丝口灯头的螺旋套只准接零线的规定，和保险丝接在火线上，三孔插座的1孔接地线，3孔接火线，2孔接零线的要求进行连线。
2.（2019•河北）如图所示，电路中打“×”处表示断路之处，若开关S闭合后，用试电笔测试电路中A、B、C点，则不能使试电笔氖灯发亮的点是________。
【答案】C
【解析】试电笔氖管若能发光，则它必须直接或间接地与火线接触，从题图所示看，A、B均与火线接触，只有C点不发光。

3.（2018•广西）某同学家室内的电灯均正常工作，当他把“220V 8W”的台灯插头插入插座后，闭合台灯开关，室内电灯全部熄灭，发生这一现象的原因可能是( )
A．插座处短路 B．台灯插头处短路 C．台灯开关处短路 D．台灯灯头处短路 【答案】D
【解析】从题意可判断，电路是发生了短路故障，由于插入台灯后，闭合台灯开关时，室内电灯才全部熄灭，所以排除插座和台灯插头处的短路；台灯的开关短路，它相当于开关闭合，不会导致电源短路，所以答案为D。
5.（2017•巴彦淖尔中考）如图所示的电路中，正常发光的三盏灯突然全部熄灭，经检查保险丝完好，用试电笔插进插座的两孔，氖管均发光。造成这一现象的原因是（ ）
A．插座发生短路了 B．进户的零线断了 C．进户的火线断了 D．某盏电灯的灯丝断了
【答案】B
【解析】试电笔能亮，说明火线上有电，而零线上本该不亮，但也亮了，说明是进户线的零线开路了，故B正确；插座处发生短路，会使保险丝熔断，故A错；进户线的火线断了，试电笔的氖管不会发光，故C错；因各灯并联，互不影响，某个电灯的灯丝烧断了，其它灯仍还亮，故D错。 6.（2017•通辽中考）请同学们将图连成符合安全用电原则的照明电路．
【答案】如图所示
2
【解析】（1）三孔插座的接法：上孔接地线；左孔接零线；右孔接火线。保险丝接火线。
（2）灯泡接法：火线进入开关，再进入灯泡顶端的金属点，零线直接接入灯泡的螺旋套，这样在断开开关能切断火线，接触灯泡不会发生触电事故，既能控制灯泡，又能更安全。 考点二、安全用电
7.（2018•广东）下列关于安全用电的说法中，正确的是( ) A．所有家用电器的外壳一定要接地
B．低压带电体和高压带电体都可以接近，但不能接触 C．电灯的开关，应该接在火线和电灯之间
D．接大功率用电器的插座，只在连接插座的零线上装一根保险丝 【答案】C
【解析】通常情况下，有金属外壳的家用电器，为了避免电器漏电，需要使用三孔插座，把用电器金属外壳跟大地连接起来，并不是所有用电器的外壳都需要接地，因此选项A是错误的；低压带电体不能接触，靠近一些没有什么危险，但高压带电体不能靠近，如果接近高压带电体，就会产生高压电弧触电，因此选项B 是错误的；电灯的开关应该接在火线与电灯之间，这样断开开关后，电灯就不带电了，人接触电灯就不会触电，所以选项C 正确；不论什么用电器，都不能在连接零线的一段接保险丝，因为如果保险丝熔断，电路中没有电流，用电器不工作，而用电器仍然跟火线连通，反而更容易触电，所以选项D是错误的。 8.（2018•安徽）停在高压输电线（裸线）上的小鸟不会触电，这是因为( ) A、鸟是绝缘体，不会导电
B、鸟的生命力特别强，不怕高压电
C、鸟停在一根电线上，两爪之间电压很低
D、鸟必须用一只脚站在电线上，否者就能触电。 【答案】C
【解析】小鸟和人一样也是导体，小鸟两爪站在同一根高压线上，且靠得很近，而导线电阻很小，相当于把小鸟两爪间短路，因而这两点间电压很小，几乎为零，所以小鸟不会触电。故选答案C。
9.（2017•邢台）某同学家中原来电灯都正常发光，当把一个开关断开的台灯插头插入插座中，保险丝断，室内电灯全部熄灭，其原因可能是（） A、台灯的功率过大 B、台灯内灯泡短路 C、插座原已短路D、台灯的插头短路
3
【答案】D
【解析】保险丝断是因为电路中电流过大，台灯开关已断开，台灯未接入电路，台灯的功率的大小，灯泡是否短路，不是引起电流过大的原因，故排除A与B项，原来电灯正常发光，说明插座原来没有短路，故排除C项。惟一可能的是插头短路，插入插座后引起家庭电路短路，故答案选D。 10.（2018•保定）（多选）下面哪种情况会发生触电( ) A、人站在地上，一手接触正常零线 B、人站在地上，一手接触火线 C、人站在绝缘体上，一手接触火线
D、人站在绝缘体上，一手接触火线，一手接触零线 【答案】BD
【解析】人站地上接触零线时，零线和地之间没有电压，所以人不会触电，人站在绝缘体上，一手接触火线时，电路中人体和大地间是断路，因此也不会触电。人站在地上，一手接触火线或两手分接火线，零线，使电路构成通路，所以能发生触电。
1．(2018·辽宁)下面的哪些图示情况会发生触电事故（）
A．甲与乙 【答案】B
B．甲与丙 C．乙与丙 D．丙与丁
【解析】触电的实质是有电流通过人体，即人直接或间接与火线连通。甲图，人的两只手分别接触火线和零线，电流会通过人体而触电；乙图，人虽然接触火线，但下方的椅子是绝缘体不导电，所以电流不能形成通路，不会触电；丙图，人手接触火线，且人与大地连通，电流会通过人体而触电；丁图，人手接触零线，但零线与大地间没有电压，所以不会有电流通过人体，不会触电。故甲、丙会发生触电事故，B正确。 2．（2017•大连）将如图所示完好的接线板连入家庭电路中，闭合开关S，指示灯发光。再将台灯插入接线板上的插座，台灯与指示灯都能发亮，则（）
4
A．该接线板的连接线内只有火线和零线两根导线 C．台灯与指示灯并联，开关S在干路上 光 【答案】C
B．台灯与指示灯串联，并受开关S控制
D．该接线板上有5个插孔会使检测的测电笔氖管发
【解析】根据图示可知，该插座有三孔插座，插头为三脚插头，因此相连的线有火线、零线和地线，故A错误；开关控制台灯和指示灯，而台灯和指示灯互不影响，因此台灯与指示灯并联，开关S在干路上，故B错误、C正确；从接线板上可以看出，三个三孔插座，三个两孔插座，因此一共有六个插孔与火线相连，即六个插孔能使测电笔氖管发光，故D错误。
3．（2018•广东）电工师傅常用一只标有“220 V 40 W”的灯泡L0(检验灯泡)放在如图位置来检查新安装的照明电路中每个支路的情况。当只闭合S、S1时L0不亮；当只闭合S、S2时，L0和L2都呈暗红色；当只闭合S、S3时，L0正常发光。由此可以判断（）
A．L1所在的支路短路 B．L2所在的支路断路 C．L3所在的支路短路 D．各支路均完好 【答案】C
【解析】分析电路图，当闭合S和任一支路的开关时，灯泡L0和该支路灯泡串联，所以如果灯不亮，表明支路存在断路；如果两灯呈暗红色，表明支路正常；如果L0正常发光，说明两端电压为220 V左右，即该支路存在短路。故L1所在的支路存在断路故障；L2所在的支路正常；L3所在的支路短路。故C符合题意。 4．（2018•河南）下列情况不会造成触电事故的是（） A．人站在地上，一只手接触火线
B．人站在地上，两只手同时接触火线
D．人站在绝缘凳上，一只手接触火线，另一只手接触零线
C．人站在地上，两只手同时接触零线 【答案】C
5
【解析】A．由于大地是导体，所以人站在地上，一只手接触火线时，会有电流通过人体，故发生触电事故；B．由于大地是导体，所以人站在地上，两只手同时接触火线时，会有电流通过人体，故发生触电事故；C．由于理论上说，零线和大地之间没有电压，所以人站在地面上，两只手接触零线不会发生触电事故；D．由于人体是导体，所以人站在绝缘凳上，一只手接触火线，一只手接触零线，此时会有电流通过人体，故发生触电事故；故选C。
5．（2017•石家庄）如图是小明常用的一个插线板。他在使用中发现：插线板上的指示灯在开关断开时不发光，插孔无法正常工作；在开关闭合时指示灯发光，插孔可正常工作；如果指示灯损坏，开关闭合时插孔也能正常工作。根据上述现象，你认为开关、指示灯和插孔的连接方式是下列几幅图中的（）
A． B．
C． D．
【答案】D
【解析】由题，在开关闭合时指示灯发光，插孔可正常工作；如果指示灯损坏，开关闭合时插孔也能正常工作。说明指示灯和插孔互不影响，二者是并联的，开关应该在干路上，故AB错误。开关接在指示灯、插孔和火线之间，控制火线使用更安全，插座应符合“左零右火”。故只有D正确。 6．（2017•保定）在家庭电路中，从进户线起连接顺序正确的是（）
A．闸刀开关、电能表、保险盒、插座 B．闸刀开关、电能表、插座、保险盒 C．电能表、闸刀开关、保险盒、插座 D．电能表、保险盒、闸刀开关、插座 【答案】C
【解析】家庭电路主要由进入家庭的进户线、电能表、闸刀开关、保险盒、开关、插座、用电器组成。且进户线、电能表、闸刀开关、保险盒的顺序不能颠倒，故从进户线起连接顺序正确的只有C，故选C。 7．（2018•广东）小明同学家的电路简化后的示意图如图所示，关于该电路，下列说法正确的是（）
6
A．家庭电路中交流电的频率是50 Hz，电压为220 V B．白炽灯、电视和台灯是串联在电路中的 C．去掉空气开关不影响电路的工作和安全 【答案】A
【解析】我国家庭电路中交流电的频率是50 Hz，电压为220 V，故A正确；白炽灯、电视和台灯工作时互不影响，是并联在电路中的，故B错误；空气开关对电路起到保护作用，去掉空气开关一般不影响电路的正常工作，但一旦出现短路或干路电流过大时，会严重影响电路的安全，故C错误；电能表是直接测量电功的仪表，故D错误，故选A。
8．（2017•辽宁）如图所示的家庭电路中，闭合开关S，电灯正常发光。用测电笔测量灯座里的两个接线柱
D．电能表是直接测量电功率的仪表
B、C时，测电笔的发光情况是（）
A．B点亮、C点不亮 【答案】A
B．C点亮、B点不亮 C．B、C点都亮 D．B、C点都不亮
【解析】闭合开关S，电灯正常发光。从图中可以看出，C点与零线相连，B点与火线相连，因此用测电笔进行测量时，B点亮，C点不亮。故A正确为答案。
9．（2018•河南）如图是停落在裸露电线上的两只小鸟，下列有关它们的说法中错误的是（）
A．若灯泡断路，闭合开关，两只小鸟都触电 B．闭合开关，乙小鸟会触电
C．若小灯泡短路，闭合开关，两只小鸟都不会触电 D．若甲小鸟两爪间的电线断了，闭合开关，两只小鸟都会触电
7
【答案】A
【解析】若灯泡断路，乙小鸟串联在电路中，有电流通过，会触电，而甲小鸟的两脚之间为很短的一段导线，电阻很小，所以两脚之间电压很小，可以忽略不计，故甲不会触电，故A错误；电路正常，闭合开关，乙小鸟的两脚与灯并联，两脚间电压为电源电压，会有电流流过小鸟，会触电，故B正确；若小灯泡短路则整个电路为一根导线，小鸟两脚间电压都非常小，可以忽略不计，两小鸟都不会触电，故C正确；若甲小鸟两爪间的电线断了，乙小鸟与灯并联后，再与甲小鸟串联，两只小鸟的两脚间都会有电压，故会有电流流过小鸟，两只小鸟都会触电，故D正确。 10.（2018•山西）利用所学知识解决下列问题：
①家庭电路中的保险丝断了，能用铜丝或铁丝替代保险丝吗？为什么？
②把灯泡接入电路，灯泡和跟它相连的导线都要发热。灯泡热得发烫，导线的发热却察觉不出来。这是为什么？
③一个灯泡的灯丝断了，把断了的灯丝搭在一起，灯泡会更亮。怎样解释这个现象？
【答案与解析】①、不能，因为铜丝或铁丝的电阻率小，跟保险丝比，根据Q=IRt，在电流和时间相同时，产生的热量小得多；并且铜丝或铁丝的熔点高，不易熔化。所以，铜丝或铁丝在电流大的时候不能
及时熔断电路，起不到保险的作用。
②、通过灯泡和导线的电流和通电时间相同，灯泡的电阻比导线的要大得多，根据Q=IRt，灯泡上通电产
生的热量就要大得多。
③、灯丝搭上后连入电路的灯丝变短，电阻变小，而家庭电路电压不变，根据P=U/R，电功率会变大，所
以亮度变大。赠送中考英语
