TASK (i): Find time-domain equations for a parallel LC resonant circuit An LC resonant circuit is sometimes referred to as an LC-tank or tuned circuit. It is made up of two components: an inductor (L) and a capacitor (C), hence the name. CAPACITOR 4 e V - + V - Figure 1: Capacitor symbol The charge on a capacitor is proportional to the voltage across it, the constant of proportionality being the capacitance C, measured in Farads (F). Since current...
