Parallel RLC circuit
= Parallel RLC circuit
{title2=$Y(\omega)$}
An ideal <resistor>, <inductor> and <capacitor> connected across the same <voltage> have admittance $Y=1/R+i(\omega C-1/(\omega L))$ in the $e^{i\omega t}$ convention. At $\omega_0=1/\sqrt{LC}$ the reactive branch currents cancel, giving minimum source current $V_0/R$ and maximum impedance $R$. This differs from a lossy series coil placed across a <capacitor>.
