What is the effect of temperature on the resistance in a Wheatstone bridge?
Correct Answer: Resistance increases with temperature in most conductors.
- Step 1: Understand what a Wheatstone bridge is. It is a circuit used to measure unknown resistances.
- Step 2: Know that resistance is how much a material opposes the flow of electric current.
- Step 3: Learn that temperature can affect resistance. For most materials, as temperature increases, resistance also increases.
- Step 4: Recognize that this change in resistance can affect the readings in a Wheatstone bridge.
- Step 5: Conclude that if the temperature goes up, the resistance in the Wheatstone bridge will likely increase, affecting the balance of the bridge.
