Resistance of a given wire is obtained by measuring

Asked by admin @ 16/08/2021 in Physics viewed by 347 People

Resistance of a given wire is obtained by measuring the current flowing in it and the voltage differenceapplied across it. If the percentage errors in the measurement of the current and the voltage differenceare 3% each, then error in the value of resistance of the wire is

Answered by admin @ 16/08/2021

In multiplication or division, percentage errors are simply added
Since R=V/I

% error in R= % error in V + Percent error in I
= 3%+3%
= 6 %
