series

• • potential difference is shared between components
  • V(total) = V(1) + V(2)…
  • the current is the same in each component
  • the total resistance of two components is the sum of resistance of each component
• • the total resistance of two components is the sum of each resistance component
  • adding a resistor means potential difference has to be shared
  • potential difference is lower, so, current is lower
  • current same everywhere so total current reduced
  • total resistance of circuit increases
