Q

What is the total voltage when 12 Nickel-Cadmium batteries are connected in series?

🔍 Key Concepts

• Series connection of batteries and how voltages add • Typical nominal voltage of a single Nickel-Cadmium (Ni-Cd) cell • Difference between cells vs. batteries in electrical terminology

💭 Think About

• First, recall the standard nominal voltage of one Ni-Cd cell. What is it approximately? • If you connect multiple sources in series, what happens to the total voltage? Do you add, average, or keep it the same? • Multiply the nominal voltage of one Ni-Cd unit by 12. Which answer choice is closest to that value?

✅ Before You Answer

• Be clear whether the question means 12 individual Ni-Cd cells or a 12-volt battery made of Ni-Cd cells inside; the exam usually treats each as one cell of nominal voltage. • Confirm you know the nominal cell voltage typically used in DC circuit problems for Ni-Cd chemistry. • After you calculate, check which option matches your result; make sure it is significantly higher than a single cell’s voltage because they are in series.
