If RR is the total resisteance of three resistors, connected in parallel, with resistances R1R1, R2R2, R3R3, then 1R=1R1+1R2+1R31R=1R1+1R2+1R3If the resistances are measured in ohms as R1R1 = 15Ω15Ω, R2R2 = 20Ω20Ω, and R3R3 = 35Ω35Ω, with a possible error of 0.4% in each case, estimate the maximum error in the calculated value of RR.
