Detailed Solution
Download Solution PDFமின்தேக்கியின் முக்கியமான பண்பு என்னவென்றால், அது AC சிக்னலைக் கடந்து, DC சிக்னலைத் தடுக்கிறது.
நிரூபிக்க:
மின்தேக்கியின் எதிர்வினை:
\({X_C} = \frac{1}{{j\omega C}}\)
இங்கே, ω = கோண அதிர்வெண்
C = கொள்ளளவு
DC சிக்னலுக்கு, ω = 0, அதனால் XC எல்லையற்றது (கோட்பாட்டளவில்).
AC சிக்னலுக்கு, ω = ω1 என்று வைத்துக்கொள்வோம். இப்போது ω1 பெரியதாக இருந்தால், XC சிறியதாக இருக்கும், அதனால் மின்மறுப்பு குறைவாக இருக்கும்.
எனவே, AC சிக்னல் மின்தேக்கி வழியாக செல்லும் ஆனால் அது DC சிக்னலை தடுக்கிறது.
