A current carrying conductor obeys Ohm's law \((V=R I)\). If the current passing through the conductor is \(I=(5 \pm 0.2)\) A and voltage developed is \(V=(60 \pm 6) \mathrm{V}\), then find the percentage of error is resistance, \(R\)
- A 18
- B 6
- C 14
- D 2
Answer & Solution
Correct Answer
(C) 14
Step-by-step Solution
Detailed explanation
Given, current passing through the conductor, \(I=(5 \pm 0.2) \mathrm{A}, \Delta I=0.2 \mathrm{~A}\) Voltage developed, \(\begin{array}{rlrl} & & V & =(60 \pm 6) \mathrm{V} \\ \Rightarrow \quad & \Delta V & =6 \mathrm{~V} \end{array}\) By Ohm's law,…
