A fixed inductance L 1.07 ?H is used in series with a variable capacitor in the tuning section of a radio telephone on a ship. What capacitance tunes the circuit to the signal from a transmitter broadcasting at 6.90 MHz?answer in pFhow to solve this would be great :) a few step by steps maybe Thanks!
The natural (resonant) frequency (f?) of a LC circuit is given by . f? 1/(2π√LC) Find the value of C that gives a frequency 6.90^6 Hz . (f?)? 1/(4π?LC) C 1/(4π?L.f??) . C 1/(4π? x 1.07^-6H x [6.90^6Hz]?) . . ?C 4.97^-10F (0.497pF/0.50pF)
The Physics communicate board, as at present constituted, is so heavily greater advantageous than the Astronomy and area communicate board. AS has a tendency to be exceptionally gentle. multiple i. Grade college homework, ii. Hoaxes (2012 stuff), and iii. Trolls surfing for interest. even regardless of the undeniable fact that homework help is annoying, on the least it somewhat is serious. which you will possibly have the potential to frequent self-clear out to seek for out questions that present day somewhat a wager and a questioner who's appreciative. there has been communicate among the aficionados of bobbing up a considerable Physics and Math communicate board. however the known consensus replace into that it would even regardless of the undeniable fact that be full of homework questions and direct mail trolls, and Y!A might now not be keen on the belief thinking what Y!A needs is site visitors.
