The resistance of a metal is given by R = V/I, where V is potential difference and I is the current. In a circuit, the potential difference across resistance is $V=(8\pm 0.5)\mathrm{V}$ and current in resistance, $I=(4\pm 0.2)\mathrm{A}$. What is the value of resistance with its percentage error?

• A

  $(2\pm 5.6\mathrm{\%})\mathrm{\Omega }$

• B

  $(2\pm 0.7\mathrm{\%})\mathrm{\Omega }$

• C

  $(2\pm 35\mathrm{\%})\mathrm{\Omega }$

• D

  $(2\pm 11.25\mathrm{\%})\mathrm{\Omega }$
