🔍 Key Concepts

• I²R losses (resistive heating) in electrical conductors and internal resistance of battery cells • How chemical reactions inside a storage battery convert electrical energy to chemical energy (charging) and vice versa (discharging) • The difference between electrical losses and intended energy conversion in a battery

💭 Think About

• When current flows through a resistance, what happens to some of the electrical energy? How is this related to I²R? • During a battery’s normal chemical reaction (charge or discharge), does any of that energy conversion show up as heat, even if there were no resistive losses? • Are the causes of heating in a battery strictly "losses," or can normal operation also produce heat?

✅ Before You Answer

• Identify whether I²R losses alone can explain all heating in a battery under charge/discharge • Decide if chemical reactions themselves can release or absorb heat in addition to electrical work • Confirm if more than one mechanism can simultaneously contribute to the temperature rise in a storage cell
