In a circuit \( L, C \) and \( R \) are connected in series with an
P alternating voltage source of frequency \( f \). The current

W leads the voltage by \( 45^{\circ} \). The value of \( C \) is
(1) \( \frac{1}{2 \pi f(2 \pi f L+R)} \)
(2) \( \frac{1}{\pi f(2 \pi f L+R)} \)
(3) \( \frac{1}{2 \pi f(2 \pi f L-R)} \)
(4) \( \frac{1}{\pi f(2 \pi f L-R)} \)
