newly found--> R= R1*R2*...*Rn/R1+R2+...+Rn !!!"

this formula wont work for 1/R1 + 1/R2 + 1/R3..

huh ur rite lol
sorry the question i solved only had 2 resistors in it ...  :o

~~~~shreyapril~~~~:
u can do it like (R1+R2+R3...+Rn)/(R1*R2*R3...*Rn)!!!


why isnt this possible!!

1/R1 + 1/R2 + 1/R3 doesnt simplify to that u've posted

~~~~shreyapril~~~~:
ohh ya!!
when in tried it! i gt the ans!!
true!
better to use orginal formulae!!

guys this one is a much easier method to find the conbined resistance of a parallel circuit:

(R1*R2)/(R1+R2)
