🔍 Key Concepts

• Kirchhoff’s Voltage Law (KVL) for DC circuits • Relationship between source voltage and voltage drops across resistors in series • Principle of conservation of energy in an electrical loop

💭 Think About

• If you walk once around a complete DC circuit and add up all the rises and drops in voltage, what must the net change be when you get back to your starting point? • How does the source voltage relate to the sum of all the individual voltage drops across components in a simple series circuit? • In a closed loop, can the circuit continuously gain or lose net energy each time you go around? What does that imply about the total voltage change around the loop?

✅ Before You Answer

• Recall that KVL states something specific about the algebraic sum of voltages around any closed loop. • Think about the sign convention: a voltage rise at the source versus voltage drops across loads – what happens when you add them all together? • Ask yourself which option correctly reflects a finite, balanced sum consistent with conservation of energy in a closed loop.
