ধারণা:

সাইনোসয়েডাল পর্যায়ক্রমিক ভোল্টেজের ক্ষেত্রে,

\({V_m} = \sqrt 2 \times {V_{RMS}}\)

ω = 2 π f

এখানে,

Vm = ভোল্টেজের সর্বোচ্চ বা সর্বোচ্চ মান

VRMS = ভোল্টেজের RMS মান

ω = তরঙ্গদৈর্ঘ্য

f = সরবরাহের কম্পাঙ্ক

গণনা:

 

 

\({V_m} = \sqrt 2 \times 200 = 282.2\;V\)

ω = (2π) (50) = 314 রেডিয়ান/সেকেণ্ড
