1. The problem statement, all variables and given/known data (in picture) 2. Relevant equations V=IZ All the ratio formulas (i.e. V2/V1 = N2/N1) 3. The attempt at a solution I thought V1 would be 1000 Vrms. Well the answers are shown and it's not. So I thought maybe I would multiply Vrms (1000) by root 2 to find Vpeak (Vrms = Vpeak/root 2). Didn't work. I know if I find V1, the rest will fall into place because from there, it's simple ratios. But it's getting the answer of 790.6cos(18.43) that I'm having trouble with . . .
