Q: Which of the following statements is true about a Wheatstone bridge?
Solution:
A Wheatstone bridge can be used to measure both AC and DC resistances.
Steps: 5
Show Steps
Step 1: Understand what a Wheatstone bridge is. It is a circuit used to measure unknown electrical resistances.
Step 2: Know that a Wheatstone bridge consists of four resistors arranged in a diamond shape with a voltage source and a galvanometer.
Step 3: Recognize that the bridge can balance when the ratio of the resistances is equal, allowing for accurate measurement.
Step 4: Learn that the Wheatstone bridge can be used with both alternating current (AC) and direct current (DC) sources.
Step 5: Conclude that the statement 'A Wheatstone bridge can be used to measure both AC and DC resistances' is true.
