In a circuit $L, C$ and $R$ are connected in series with an alternating voltage source of frequency $f$ . The current leads the voltage by $4 5^{\circ}$ . The value of $C$ is:NEET 2005

Options:

Answer:

Solution:

$tan ϕ tan (\frac{π}{4}) \Rightarrow R (R + 2 π f L) C = \frac{X _{C} - X _{L}}{R} = \frac{\frac{1}{ω C} - ω L}{R} = \frac{1}{ω C} - ω L = \frac{2}{2 π f C} = \frac{1}{2 π f ( R + 2 π f L )}$
