Questions & Step-by-Step Solutions

In a practical Wheatstone bridge, what is the effect of temperature on the resistors?
  • Step 1: Understand that a Wheatstone bridge is a circuit used to measure resistance.
  • Step 2: Know that resistors are components that resist the flow of electric current.
  • Step 3: Recognize that the resistance of a resistor can change with temperature.
  • Step 4: Realize that if the temperature increases, the resistance of some materials may increase or decrease depending on the type of material.
  • Step 5: Understand that if the resistance values change, the balance of the Wheatstone bridge can be affected.
  • Step 6: Conclude that temperature changes can lead to inaccurate measurements in the Wheatstone bridge.
