Answer 2

• 0.03 Ω is the correct option.

Given:

Resistance of wire = 6 ± 0.5% Ω

To Find:

The absolute error in resistance.

Solution:

According to the question,

The absolute error is 0.5 % of the actual value of the resistance of the wire.

So, 0.5 % of 6 is,

                         $=\cfrac{0.5}{100} *6\\= 0.005 * 6\\=0.03$

Hence the absolute error is 0.03 Ω.

The absolute error is added and subtracted from the actual value accordingly. This is one of the reasons why it is written after that symbol.
