 Click here to see ALL problems on Miscellaneous Word Problems Question 78491: The combined resistance of two resistors R 1 and R 2 in a parallel circuit is given by the formula Rt=_1______ 1/R1+1/R2 Simplify the formula The Rt, R1 and R2 have the t,1 and 2 below the R. I am confused as to what this means. First time I've seen them written like this before. Help!!!Answer by stanbon(57967)   (Show Source): You can put this solution on YOUR website!Rt=_1/[1/R1+1/R2] Rt = 1/[(R1+R2)/R1R2] Rt = (R1R2)/(R1+R2) -------------- cheers, Stan H.
