Alternating Current

In an LCR series circuit, an inductor 30 mH and a resistor 1 \(\Omega\) are connected to an AC source of angular frequency 300 rad/s. The value of capacitance for which, the current leads the voltage by 45\(^\circ\) is \({1 \over x} \times {10^{ - 3}}\) F. Then the value of x is ____________.
