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).

hi neobrain, welcome :)

OK for a start remove the battery and draw the waveform expected out of the diode

then consider what the battery is very similar to ... another component with 2 plates
what do you know about what happens when that other component is placed across the output of a half-wave rectifier ?

cheers
