并联电路总电阻的倒数,等于各个支路电阻的倒数之和。用公式表示为:1/R=(1/R_1)+(1/R_2)+…+(1/R_n)(1)当各支路电阻相等时,R_1=R_2=…=R_n,则 R=R_1/n(2)一般说来,实验的并联电路各支路电阻
The reciprocal of the total resistance of the parallel circuit is equal to the sum of the reciprocals of the resistance of each branch. The formula is expressed as: 1/R=(1/R_1)+(1/R_2)+...+(1/R_n) (1) When the resistance of each branch is equal, R_1=R_2=...=R_n, then R= R_1/n(2) In general, the experimental parallel circuit resistance of each branch
