If r is the total resistance of three resistors, connected in parallel, with resistances r1, r2, r3, then 1 r = 1 r1 + 1 r2 + 1 r3 . if the resistances are measured in ohms as r1 = 64 ω, r2 = 20 ω, and r3 = 8 ω, with a possible error of 0.5% in each case, estimate the maximum error in the calculated value of r. (round your answer to three decimal places.)

Explanation:

Resistance is given of different values

now we have

possible error in all resistance is 0.5 %

now we know that

Now the maximum possible error when all resistance is connected in series

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.
