12、如LED的驱动电源。电流的大小和方向都随时间作周期变化的就是交流电，通常所指的交流电是正弦波交流电，如220V电源就是正弦交流电。直流电与交流电可以形象地比喻为推着自行车走（用手朝一个方向推）和骑自行车（双脚上下循环）。直流电的基本参数是电压，交流电的基本参数除电压外还有频率，如一般的220V电是50Hz，表示1秒钟变化50个周期。电流是在有用电器的情况下才会产生，没有用电器就没有电流。如一个12V/1A的电源，在没接负载时就没有电流，接额定负载时就有1A的电流，接一半的负载就有0.5A的电流，但它的电压是不变的。二功率因数所谓功率因数，是指交流电路中，两端电压U与其中电流I之间的位相差的余弦
13、，即电压与电压不是同步变化，相差越大，功率因数就越低，直流电中因电流方向是固定的，因此没有功率因数。功率因数是0.5，可以理解为有50%的电能在用电器与发电机之间来回流动，不能利用，也不消耗掉，因此也就是需要两倍与用电器功率的发电机及供电线路来供电，或者说从发电机出来的电能只有50%可以利用。比喻：用滑轮向高处运物品，桶重50公斤，物品重50公斤，则要用100公斤的力才能把物品拉上去；但如果在拉的一端也挂上50公斤的配重，则只要50公斤的拉力就可以把物品拉上去，这就是功率因数补偿。三电阻1电阻的功用电阻在电路中起限止电流的作用，即把某个部位的电流限止在一定的电流值。电阻的阻值越大，就越能限止电
14、流通过，加同样的电压，它的电流就越小。电阻在限止电流通过的同时，多余的电能就在电阻上以热量的形式散发出来，因此电阻要发热，但发热量小于1/4W时感觉不到热量，大于1/4W时就要选择比实际发热量稍大功率的电阻。2电阻的单位电阻在线路中的代号为“R”，基本单位符号为“”，汉语读音为“欧姆”；小于1时可用m(毫欧）；大于1000时一般用“k”（千欧）,简写“K”；大于1000K时一般用“M”（兆欧）,简写“M”。它们的换算关系为； 1m=0.001 1M=1000K=3电阻的种类和功率 电阻的种类常用有碳膜电阻、金属膜电阻、线绕电阻等；电阻的功率常用的有1/16W、1/4W、1W、2W、5W-等，1
15、/16W2W一般凭体积设别，阻值多用色环表示，大于2W的一般标出功率值和电阻值；在线路中如无功率标名，一般为1/4W。电阻的外型一般为圆柱形瓷棒上做上电阻材料，并从两头套金属帽进行引线。外形电路符号4碳膜（四环）电阻色环的意义碳膜电阻共有四道色环，底色一般为灰黄色，用十二种颜色的色环来标注电阻的阻值和误差等级，误差大多为5%，这十二种颜色所代表的意义分别是：颜 色黑棕红橙黄绿蓝紫灰白金银第一环的意义-123456789-第二环的意义0123456789-第三环的意义1001011021031041051061071081090.10.01第四环的意义（误差）-5%10%如某一电阻的色环分别是：棕、绿、黄、金则电阻值为15104=，简写150k，误差为不大于5%。5金属膜（五环）电阻色环的意义金属膜电阻共有五道色环，底色一般为蓝或绿色，用十二种颜色的色环来标注电阻的阻值和误差等级，误差大多为1%或2%，这十二种颜色所代表的意义分别是：颜 色黑棕红橙黄绿
