已知公式1/R=1/r1+1/r2(r1+r2≠0)则R=?已知公式1/R=1/r1+1/r2(r1+r2≠0)则R=?已知公式1/R=1/r1+1/r2(r1+r2≠0)则R=?1/R=(r1+r2
已知公式1/R=1/r1+1/r2(r1+r2≠0)则R=?
已知公式1/R=1/r1+1/r2(r1+r2≠0)则R=?
已知公式1/R=1/r1+1/r2(r1+r2≠0)则R=?
1/R=(r1+r2)/r1r2
故R=r1r2/(r1+r2)
R=(r1*r2)/(r1+r2)
(r1*r2)/(r1+r2)
1/R=(r1+r2)/r1r2
故R=r1r2/(r1+r2)
这是电阻并联的公式
