Question 1 of 27070

To increase the power output of a storage cell:

🔍 Key Concepts

• Battery internal resistance and how it affects current flow • Relationship between terminal voltage, load, and power output (P = V × I) • What happens to voltage under load when internal resistance is high vs low

💭 Think About

• If you want more power from a cell feeding a load, what combination of voltage at the terminals and current through the load do you want? • How does internal resistance inside the cell act compared to an external resistor in series with the load? • If internal resistance increases, what happens to the voltage drop inside the cell and the terminal voltage under load?

✅ Before You Answer

• Write a simple series circuit: cell internal resistance + external load, and compare where the voltage drops occur. • Use P = V × I and Ohm’s Law (V = I × R) to see how changing internal resistance changes power delivered to the external load. • Decide whether a high or low internal resistance and voltage drop under load helps deliver more power to the external circuit.
