欧姆定律的应用:
①同一电阻的阻值不变,与电流和电压无关,其电流随电压增大而增大.(R=U/I)
②当电压不变时,电阻越大,则通过的电流就越小.(I=U/R)
③当电流一定时,电阻越大,则电阻两端的电压就越大.(U=IR)
电阻的串联有以下几个特点:(指R1,R2串联,串得越多,电阻越大)
①电流:I=I1=I2(串联电路中各处的电流相等)
②电压:U=U1+U2(总电压等于各处电压之和)
③ 电阻:R=R1+R2(总电阻等于各电阻之和)如果n个等值电阻串联,则有R总=nR
④ 分压作用:=;计算U1,U2,可用:;
⑤ 比例关系:电流:I1:I2=1:1 (Q是热量)
电阻的并联有以下几个特点:(指R1,R2并联,并得越多,电阻越小)
①电流:I=I1+I2(干路电流等于各支路电流之和)
②电压:U=U1=U2(干路电压等于各支路电压)
③电阻:(总电阻的倒数等于各电阻的倒数和)如果n个等值电阻并联,则有R总=R
④分流作用:;计算I1,I2可用:;
⑤比例关系:电压:U1:U2=1:1 ,(Q是热量)
六, 电功和电功率
1. 电功(W):电能转化成其他形式能的多少叫电功,
2.功的国际单位:焦耳.常用:度(千瓦时),1度=1千瓦时=3.6×106焦耳.
3.测量电功的工具:电能表
4.电功公式:W=Pt=UIt(式中单位W→焦(J);U→伏(V);I→安(A);t→秒).
利用W=UIt计算时注意:①式中的W.U.I和t是在同一段电路;②计算时单位要统一;③已知任意的三个量都可以求出第四个量.还有公式:=I2Rt
电功率(P):表示电流做功的快慢.国际单位:瓦特(W);常用:千瓦
公式:式中单位P→瓦(w);W→焦;t→秒;U→伏(V),I→安(A)
利用计算时单位要统一,①如果W用焦,t用秒,则P的单位是瓦;②如果W用千瓦时,t用小时,则P的单位是千瓦.
10.计算电功率还可用右公式:P=I2R和P=U2/R
11.额定电压(U0):用电器正常工作的电压.另有:额定电流
12.额定功率(P0):用电器在额定电压下的功率.
13.实际电压(U):实际加在用电器两端的电压.另有:实际电流
14.实际功率(P):用电器在实际电压下的功率.
当U > U0时,则P > P0 ;灯很亮,易烧坏.
当U < U0时,则P < P0 ;灯很暗,
当U = U0时,则P = P0 ;正常发光.
15.同一个电阻,接在不同的电压下使用,则有;如:当实际电压是额定电压的一半时,则实际功率就是额定功率的1/4.例"220V100W"如果接在110伏的电路中,则实际功率是25瓦.)
16.热功率:导体的热功率跟电流的二次方成正比,跟导体的电阻成正比.
17.P热公式:P=I2Rt ,(式中单位P→瓦(W);I→安(A);R→欧(Ω);t→秒.)
18.当电流通过导体做的功(电功)全部用来产生热量(电热),则有:热功率=电功率,可用电功率公式来计算热功率.(如电热器,电阻就是这样的.)

注1)单位换算：1A＝103mA＝106μA；1kV＝103V＝106mA；1MΩ＝103kΩ＝106Ω
(2)各种材料的电阻率都随温度的变化而变化,金属电阻率随温度升高而增大；
(3)串联总电阻大于任何一个分电阻,并联总电阻小于任何一个分电阻；
