29. (a) The batteries are identical and, because they are connected in parallel, the potential diferences across them are the same. This means the currents in them are the same. Let i be the current in either battery and take it to be positive to the leFt. According to the junction rule the current in R is 2 i and it is positive to the right. The loop rule applied to either loop containing a battery and R yields E− ir 2 iR =0 = i = E r +2 R . The power dissipated in
