🔍 Key Concepts

• Ohm’s Law and how voltage, current, and resistance are related: V = I × R • Current behavior in a series circuit (same current through every component) • How voltage divides among resistors in series depending on their resistance values

💭 Think About

• In a series circuit, if the same current flows through each resistor, how does changing the resistance affect the voltage across that resistor according to Ohm’s Law? • Compare what would happen to the voltage drop across a very small resistor versus a very large resistor when the current is the same. • Which choice matches the idea that the total supply voltage is shared among the resistors in proportion to their resistance values?

✅ Before You Answer

• Confirm that in a series circuit the current is the same through all resistors, not different for each one. • Use V = I × R to see how voltage changes when I is constant but R is different. • Verify whether position in the circuit (closest to the source or not) changes voltage drop in a true series circuit.
