In a practical Wheatstone bridge, what is the effect of temperature on resistance measurements?
Temperature has no effect
Resistance increases with temperature
Resistance decreases with temperature
It depends on the material
The effect of temperature on resistance measurements in a Wheatstone bridge depends on the material of the resistors, as different materials have different temperature coefficients.

Q: In a practical Wheatstone bridge, what is the effect of temperature on resistance measurements?
Solution: The effect of temperature on resistance measurements in a Wheatstone bridge depends on the material of the resistors, as different materials have different temperature coefficients.
Steps: 6
Step 1: Understand that a Wheatstone bridge is used to measure resistance.
Step 2: Know that resistance can change with temperature.
Step 3: Recognize that different materials (like copper, aluminum, etc.) have different responses to temperature changes.
Step 4: Learn about the temperature coefficient, which tells us how much a material's resistance changes with temperature.
Step 5: Realize that if the temperature increases, the resistance of some materials will increase, while for others it may decrease.
Step 6: Conclude that when using a Wheatstone bridge, you need to consider the temperature of the resistors to get accurate measurements.
