🔍 Key Concepts

• Faraday’s law of electromagnetic induction and how changing magnetic fields relate to voltage • How batteries and galvanic cells create electrical potential • Basic idea of photoelectric effect (light causing electron movement)

💭 Think About

• For each choice, ask yourself: can this process cause electrons to move in a conductor or circuit, creating a voltage difference? • Think about common real-world devices: which ones use magnets, chemicals, or light to produce electricity? • Are these methods mutually exclusive, or are they all known, valid ways to generate electrical potential?

✅ Before You Answer

• Be sure you understand that electrical potential (voltage) means a condition that can make current flow if a circuit is completed • Verify from basic physics or electronics that each listed process is (or is not) actually used to generate electricity in real devices • Before choosing, double-check whether more than one of the listed methods is valid, and what that implies about the best answer choice
