Questions & Step-by-Step Solutions

In a practical Wheatstone bridge, what is the effect of temperature on the resistances?
  • Step 1: Understand that a Wheatstone bridge is used to measure resistance.
  • Step 2: Know that resistance is how much a material opposes the flow of electric current.
  • Step 3: Learn that conductors (like metals) have atoms that vibrate when heated.
  • Step 4: Realize that as temperature increases, these atomic vibrations become stronger.
  • Step 5: Understand that stronger vibrations make it harder for electric current to flow.
  • Step 6: Conclude that the resistance of conductors increases with temperature.
