Question: In a practical Wheatstone bridge, what is the effect of temperature on the resistances?

Options:

Correct Answer: Resistances increase with temperature

Solution:

In general, the resistance of conductors increases with temperature due to increased atomic vibrations.

In a practical Wheatstone bridge, what is the effect of temperature on the resistances?

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.

Temperature Dependence of Resistance – The resistance of conductors typically increases with temperature due to increased atomic vibrations, which affects the movement of charge carriers.
