Question

Resistance of a given wire is obtained by measuring the
current flowing in it and the voltage difference applied
across it. Ifthe percentage errors in the measurement of the
current and the voltage difference are 3% each, then error
in the value of resistance of the wire is (AIEEE 2012)
(a) 6%
(b) zero
(c) 1%
(d) 3%

Answer 1

6% as v=ir:: both v and I increased by 3% so 3+3= 6%

Answer 2

6 percent is the answer for the given question
