अवधारणा

पूर्ण और अर्ध-तरंग दिष्टकारी का औसत और RMS मान इस प्रकार दिया गया है:

पूर्ण तरंग दिष्टकारी:

\(V_{o(avg)}={2V_m\over \pi}\)

\(V_{o(rms)}={V_m\over \sqrt{2}}\)

अर्ध-तरंग दिष्टकारी:

\(V_{o(avg)}={V_m\over \pi}\)

\(V_{o(rms)}={V_m\over 2}\)

गणना

दिया गया है, Vm = 20V

औसत आउटपुट वोल्टेज इस प्रकार दिया गया है:

\(V_{o(avg)}={2\times 20\over \pi}\)

\(V_{o(avg)}=\frac{40}{\pi}V\)
