Homework Equations
Power Factor = True Power / Apparent Power
f = 1 / (2*pi*root(LC))
Z = root(R^2 + (Xl - Xc)^2) = R
The Attempt at a Solution
a)i) 1? Because it's purely resistive, but this surely can't be right, because it's 4 marks.
ii to iv) no idea
b)i)
f = 1 / (2*pi*root(LC))
f = 64.97 Hz
b)ii) I don't see how the raise in resistance effects the frequency as the resonant frequency formula doesn't contain R.
