In the battery charger circuit shown the sinewave input vs is 12 rms while the battery voltage varies from 12 v to 14 v from the discharged to fully charged states rs = 10 Ω is the charging source resistance d is an ideal diode and rc = 50 Ω is a current controlling resistor established by the designer skecth and label the diode current waveform for vb = 12 what are its peak and average and values ? what do the peak and average diode current become whem vb reaches 14 v ?
