🔍 Key Concepts

• Battery polarity (positive vs negative terminal identification) • Use of a voltmeter to determine polarity and voltage direction • Traditional salt water method used as a simple field test for DC polarity

💭 Think About

• How can the leads of a voltmeter show you which battery terminal is positive and which is negative? Think about what the meter display does when the leads are reversed. • What happens when you place two bare wire ends from a DC source into a salt water solution—what can bubbles tell you about polarity? • Consider whether the question is asking for just one method or whether more than one listed method would work in practice.

✅ Before You Answer

• Make sure you know how a DC voltmeter indicates polarity when connected across a battery. • Recall which electrode in an electrolytic solution (like salt water) produces more gas bubbles and what that says about polarity. • Check whether both listed methods are actually valid practical ways to determine battery polarity, or if one is clearly unsuitable.
