1. The problem statement, all variables and given/known data a) http://i.imgur.com/LrWxrEX.jpg b) http://i.imgur.com/3YmN3Rv.jpg 2. Relevant equations A halt-wave rectifier(a) is used to charge a battery E.The battery is rated at 12V 100Wh. Average charging current for the battery should be 5A.The primary input voltage is 120v at 60Hz and the transformer has 2 : 1 turns ratio: Determine: i) wave form for Vs, i0, Vs - E ii)The conductor angle of the diode. 3. The attempt at a solution I have not really done anything tryed to draw the graph or get the conductor angle of the diode as I am confused by what effect the battery has on the waveforms.For I full wave rectifier I have something like figure (b).
