1. The problem statement, all variables and given/known data Find Amplitude of Steady-state voltage across capacitor 2. Relevant equations 3. The attempt at a solution I'm at the very last step of changing it back into the time domain to obtain my ampltiude. I was planning on getting it into the form a + bj, then using trigonometry and other formulae to get it into polar form from which I can get it into the form of Bsin(wt + theta), with B giving me my amplitude. Im stuck with 8+ 8/20 j^-1. Which isnt in the form a+bj. Any ideas how I can try and get it into that form?
