Effects when adding to single loops(Summary)

Either make more loops, or change one loop

  • adding cells or batteries in series increases the current
  • adding cells or batteries in parallel makes them last longer
  • adding resistors or bulbs to a single loop (so necessarily with series connections) decreases the current in the battery
  • adding loops by adding more resistors or bulbs using parallel connections increases the current in the battery
  • In each case the current is set by the push provided by the batteries and the resistance of the other elements in the loops.
