PLEASE HELP! I don't understand this at all.
A series RLC circuit is connected with source providing amplitude voltage of V= 120 V. The amplitude voltages measured accross the capacitor and inductor were found to be V(c)=20 V and V(L)=80 V repectively. The resistance used has R=150 ohms.
a) what is the average power supplied by the source?

what is the frequency of the suppy, is it 50hz? without it we can have some difficulties

anonymous · Answer

It doesn't say, thus one of the reasons I am having problems

sidsiddhartha · Answer

ok then u have to assume it because without it we cannot find values of C and L
as
$$X_c=1/\omega_c=\frac{ 1 }{ 2 \pi f }\and\X_l=2 \pi f*L$$

sidsiddhartha · Answer

it will be 
$$X_c=1/2 \pi f C$$

sidsiddhartha · Answer

ok lets say f=50 hz now can u do it?
