প্রদত্ত:

উৎপন্ন তাপ = 200 জুল

রোধ = 2 ওহম

অনুসৃত সূত্র:

উৎপাপাত তাপের পরিমাণ, \(H=\frac{V^2t}{R}\)

[যেখানে V হল উৎপন্ন ভোল্টেজের পরিমাণ; t হল প্রয়োজনীয় সময়; R হল রোধ]

গণনা:

\(200=\frac{\mathrm{V}^2 \times 1}{2}\\ \Rightarrow \mathrm{V}^2=400 \\\Rightarrow \mathrm{V}=20 \mathrm{v} \)

সুতরাং, সঠিক উত্তর হল 20 ভোল্ট।
