🔍 Key Concepts

• How a dry cell battery behaves when current is flowing vs. when no current is flowing • The difference between an open-circuit (no load) voltage test and a loaded (under load) voltage test • What a conventional voltmeter actually measures when connected across a battery

💭 Think About

• Think about what you really want to know when you "test" a battery: is it the maximum possible voltage with no current, or its ability to deliver voltage while supplying current? • Consider what happens to the voltage reading of a weak dry cell when you first connect a meter with no load, and then when you connect a real load (like a light bulb). Which reading better reflects the battery’s condition? • Ask yourself whether a typical voltmeter significantly loads a dry cell, or if it mostly measures open-circuit voltage.

✅ Before You Answer

• Clarify in your mind whether "under normal load" means current is actually being drawn from the cell during the test • Decide whether a no-load (open-circuit) measurement alone can detect a weak dry cell that collapses under load • Consider whether using any conventional voltmeter by itself ensures you are really testing the cell under load, or mostly without load
