A110 V AC, 60 Hz
B415 V DC, 50 Hz
C230 V AC, 50 Hz
D415 V AC, 60 Hz
Answer & Solution
Correct answer: C. 230 V AC, 50 Hz
ভাৰতৰ ঘৰুৱা যোগান হৈছে 50 Hz-ত 230 V AC (3-ফেজ ঔদ্যোগিক = 415 V)।
আমেৰিকা যুক্তৰাষ্ট্ৰই (USA) 60 Hz-ত 110 V AC ব্যৱহাৰ কৰে।
এই কথাটো জনা থাকিলে ভ্ৰমণ কৰাৰ সময়ত বিদেশী সঁজুলিসমূহ নষ্ট হোৱাৰ পৰা ৰক্ষা পৰে।
