Just doing a few bits n bobs throughout the summer to keep active but I am seriously stumped on a Thevenin's Theorem problem. The circuit contains a single power source, one inductor one capacitor, and a single resistance.
Is there anybody the is willing to post some basic steps at tackling it? Will post the circuit as a photo. Kind regards.
