What you'll learn

  1. Balance four arms: A balanced Wheatstone bridge
  2. The metre wire: The metre bridge
  3. Swap the gaps: Swapping the gaps
  4. Add one in line: Move the null point with a new resistor
  5. Shunt to shift: A shunt lowers one gap
  6. Thicker wire: Only the ratio of lengths counts
  7. Heat one arm: A slightly unbalanced bridge
  8. Read to a millimetre: How a reading error spreads
