Q

A nickel-cadmium cell has an operating voltage of about:

🔍 Key Concepts

• Typical nominal cell voltages for different battery chemistries (lead-acid, nickel-cadmium, alkaline) • Difference between cell voltage (single cell) and battery voltage (multiple cells in series) • Standard Ni-Cd (nickel-cadmium) cell characteristics used in emergency lighting and aviation/marine applications

💭 Think About

• First recall the common nominal voltage for a single lead-acid cell, then compare that to what you remember for a Ni-Cd cell—are they the same order of magnitude? • Think about how many cells are typically used to make a 12-volt battery; what does that suggest about the voltage of each individual cell for that chemistry? • Eliminate any options that are clearly typical of a different chemistry (for example, values you strongly associate with lead-acid cells).

✅ Before You Answer

• Make sure you’re thinking of single cell voltage, not a multi‑cell battery pack voltage • Check which option matches the standard nominal voltage you’ve seen in specs for Ni-Cd cells (often used in tools, emergency lights, and older avionics) • Verify that the value you choose is less than a lead‑acid cell but in the same general range as other common rechargeable cells
