Which of the following statements is true regarding the Wheatstone bridge?
Correct Answer: The Wheatstone bridge is primarily used to measure unknown resistances by balancing it against known resistances.
- Step 1: Understand what a Wheatstone bridge is. It is a circuit used to measure electrical resistance.
- Step 2: Know that the Wheatstone bridge consists of four resistors arranged in a diamond shape.
- Step 3: Recognize that two of the resistors are known values, and one is the unknown resistor we want to measure.
- Step 4: Learn that the bridge is balanced when the voltage across the middle (between the two known resistors) is zero.
- Step 5: Use the formula for a balanced Wheatstone bridge to find the unknown resistance based on the known resistances.
