1.

resistance of two resistors is measured as( 20+- 0.2 ) ohm and (40+-0.2) ohm . the maximum absolute error in their series combination will be​

Answer»

0.4 Explanation:In general, the RULE for series circuit is that resistances ADD up in series. Let us say that we have THREE resistors Ra, Rb and Rc, thenR = Ra + Rb + RcNow if they are in parallel circuit, then net RESISTANCE reduces.Its formula is;1/R = 1/Ra + 1/Rb + 1/RcNow as per given information, when the resistors each having an error of -+0.2 are connected in series, then the MAXIMUM absolute error would be=0.2+0.2=0.4
