🔍 Key Concepts

• Ohm’s Law: $I = \frac{V}{R}$ and how it applies to a DC circuit • How total resistance is found when R1 and R2 are in series • In a series circuit, current is the same through all components

💭 Think About

• Look at figure A and trace the path from the battery through the switch, R1, and R2 when the switch is closed. Is there more than one path for current? • First find the total circuit resistance with R1 and R2 both in the circuit. Then use Ohm’s Law to find the circuit current. • Once you know the total current in a series circuit, what does that tell you about the current through R2 specifically?

✅ Before You Answer

• Confirm from the diagram that R1 and R2 are in series, not parallel. • Correctly compute total resistance before using Ohm’s Law: add series resistances directly. • After finding the circuit current, remember that in a series circuit the current through R2 equals the total current. Double‑check your arithmetic with the multiple‑choice options.
