When the spark gap to spark all C's will continue to receive the same Cb series compressor charge through R'd per series with different discharge C's with Cb through repetition and R'd R'e one.
When the spark gap spark all the C's are connected in series Cb will be charged through R'd series with C's and Cb through various discharge R'e and R'd another.
When spark gap was spark all C 's will let Cb series will be charging through the R' d connection in series with C 's with Cb. Discharge through R 'and' e R d once again.
