In the above question if `V_(S)(t)=220sqrt2 sin (2pi 50 t)`, find (a)`l(t)` ,(b)`v_(R)` and (c )`v_(C)(t)`

Text Solution

Verified by Experts

(a)`i(t)=I_(m)sin(omegat+phi)` =`sqrt2sin(2pi50t+45^(@))`
(b)`V_(R)=i_(R).R =i(t)R =sqrt2xx100 sin(100 pit+45^(@))`
( c)`V_(C)(t)=i_(C)X_(C)` (with a phase lag of `90^(@)`) =`sqrt2xx100 sin (100pit+45-90)`
