(1)R=(R1*R2)/(R1+R2)(注:R不等于R2),求R1(2)已知(S/V)-S/(V+2)=1,求S(1)R=(R1*R2)/(R1+R2)(注:R不等于R2),求R1(2)已知(S/V
(1)R=(R1*R2)/(R1+R2)(注:R不等于R2),求R1(2)已知(S/V)-S/(V+2)=1,求S
(1)R=(R1*R2)/(R1+R2)(注:R不等于R2),求R1
(2)已知(S/V)-S/(V+2)=1,求S
(1)R=(R1*R2)/(R1+R2)(注:R不等于R2),求R1(2)已知(S/V)-S/(V+2)=1,求S
原式=R(R1+R2)=R1R2
=RR1+RR2=R1R2
RR2=R1R2-RR1
RR2=R1(R2-R)
RR2/(R2-R)=R1
2: S(V+2)/V(V+2)-SV/V(V+2)=1
[S(V+2)-SV]/V(V+2)=1
2S/V(V+2)=1
2S=V(V+2)
S=V(V+2)/2
①R=(R1R2)/(R1+R2)
R1R+R2R=R1R2
R2R=R1R2-R1R
R1=R2R/(r2-r)
②等式两边同时乘以 V(V+2) 得
(v+2)S-Sv=V(V+2)
S={V(V+2) }/2
R=R*R2/(R-R2)
S=1/2V*(V+2)
1/(1/R1+1/R2),化简为R=R1*R2/(R1+R2),怎么化简的,
1/R=1/R1+1/R2 R=R1+R2/R1 R2 R=R1 R2/R1+R2 这三种关于并联电路的电阻公式
1/R=1/R1+1/R2,则用R,R1表示R2=( )
若1/R=1/R1+1/R2,则.A:R=R1+R2,B:R=R1+R2/R1+R2,C:R=R1R2/R2+R1,D:R=R1R2/R1-R2求大神帮助/是除号
R1:R2=1:4; 为什么R总=R1R2/R1+ R2=R2/5
电阻并联公式R=(R1×R2)÷(R1+R2),r2=?
1/R=1/R1+1/R2(R1≠R2)则表示R1的式子是
1/R=(R1+R2 )/ (R1R2) 中,R1不等于R2,求出表示R2的式子
R=R1/1+R2/1
R=R1//R2是什么意思?
1/R=1/R1+1/R2的变形公式是否为R=R1*R2/R1+R2
在公式1/R=1/r1+1/r2中(r1+r2≠0),用r1,r2表示R是?
在公式1/R=1/r1+1/r2中(r1+r2≠0),用r1、r2表示R是
已知1/R=R1+R2/R1R2,R1≠R2,用R、R1的分式表示R2
电阻R1、R2串联,证明R总=R1+R2
(1)R=(R1*R2)/(R1+R2)(注:R不等于R2),求R1(2)已知(S/V)-S/(V+2)=1,求S
(1)R=(R1*R2)/(R1+R2)(注:R不等于R2),求R1(2)已知(S/V)-S/(V+2)=1,求S
把式子 1/R=1/R1 +1/R2 (R1R2均不为零) 变成求R1的式子A R1=RR2/R2-R1B R1=RR2/R2+RC R1=RR1+RR2/R2D RR2/R-R2
