PHYSICS Two resistances are expressed as R_1=(4 \pm 0.5)Ω and R_2=(12 \pm 0.5)Ω . What is the net resistance when they are connected (i) in series and (ii) in parallel with percentage error ?

Correct Answer is : 16Ω±6.25%,3Ω±31.25%

16\Omega\pm23%, 3\Omega\pm6.25%

16\Omega\pm6.25%, 3\Omega\pm31.25%

3\Omega\pm23%, 16\Omega\pm6.25%

16\Omega\pm6.25%, 3\Omega\pm23%
