If the illustrated device is fully charged,...

🔍 Key Concepts

• Identify the type of battery shown (note the steel container, pocket plates, and gas release/vent caps). • Recall how specific gravity of the electrolyte behaves in this battery type compared with a lead‑acid battery. • Consider what happens to the terminal voltage of a storage battery between fully discharged and fully charged conditions.

💭 Think About

• Does this illustration look like a typical lead‑acid cell with transparent case and lead plates, or a different construction (pocket‑plate alkaline cell)? • For this battery type, is the electrolyte chemically used up and restored during charge/discharge, or does it mainly act as an ion carrier? How would that affect specific gravity readings? • When a storage battery goes from discharged to fully charged, what is the usual trend of its output voltage, even if the change is small?

✅ Before You Answer

• Verify whether specific gravity is a good indicator of state of charge for this exact battery type. • Decide if, at full charge, the terminal voltage should be higher, lower, or the same as when discharged. • Eliminate any choices that claim both specific gravity and voltage behave the same way from discharged to fully charged if that conflicts with how this battery actually operates.

If the illustrated device is fully charged, what will be the result? See illustration EL-0061.

The specific gravity will be at a maximum value and the output voltage will be at a maximum value.

The specific gravity will be unchanged and the output voltage will be at a maximum value.

The specific gravity will be at a maximum value and the output voltage will remain unchanged.

The specific gravity and the output voltage will remain unchanged.
