there is a parallel R - C circuit connected with a alternating current source of frequency 'w'.
on plotting the function of |z| vs 'w' we get max at w=0; and max/2 at 'w'= 1/RC.
while calculating power absorbed by resistor,
we get Pmax = 1/2I^2R( >>>? how)..
and at w = 1/RC power by resistor is Pmax/2.
...
,,,
my question is how can Pmax be 1/2I^2R as power is max at w = 0 and at that its a DC where
power max must be I^2R...
can some1 enlighten me in this topic pls...
also at w = 1/RC,power is 1/2 of above defined power which is easily calculated.. so it is termed as half power freq..
..?>>
thanks
