🔍 Key Concepts

• Wheatstone bridge circuit layout and purpose • Relationship between voltage, current, and resistance (Ohm’s Law) • Which electrical parameter is most commonly measured with bridge circuits for precision

💭 Think About

• What quantity is being compared between the four arms (legs) of a Wheatstone bridge when it is balanced? • In typical lab use, when you adjust a Wheatstone bridge to balance (zero the meter), what component are you actually changing? • Which of the listed parameters is most directly associated with Ohm’s Law in its basic DC form?

✅ Before You Answer

• Identify which of the four options is the basic unit used in Ohm’s Law: V = I × R • Recall what kind of unknown component is usually placed in one arm of a Wheatstone bridge during experiments • Eliminate options that are mainly associated with AC circuits or energy storage rather than simple DC precision measurement
