Question

If potential V=100 $\pm$ 0.5 V and current 1=10 $\pm$ 0.2 A are given to us. then what will be the value of resistance

• A. $10\pm 0.7\Omega$
• B. $5\pm 2\Omega$
• C. $0.1\pm o.2\Omega$
• D. None of these

Answer 1

The correct option is A $10\pm 0.7\Omega$

From ohm's Law we know $R=\frac{V}{i}$

According to question:

$R=\frac{V}{i}=\frac{100\pm 0.5}{10\pm 0.2}=10\pm 0.7\Omega$
