கருத்து:

சைன் வடிவ  மாற்று மின்னழுத்தத்திற்கு,

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

ω = 2 π f

இதில்,

Vm = மின்னழுத்தத்தின் அதிகபட்ச அல்லது உச்ச மதிப்பு

VRMS = மின்னழுத்தத்தின் RMS மதிப்பு

ω = அலைநீளம்

f = விநியோக அதிர்வெண்

கணக்கீடு:

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

ω = (2π) (50) = 314 ரேடியன்/வினாடி..
