🔍 Key Concepts

• Identify which resistors are in series and which are in parallel in figure B • Use the formula for equivalent resistance in parallel: 1/R_total = 1/R1 + 1/R2 • Remember that series resistances add directly: R_total = R_series1 + R_series2

💭 Think About

• Trace the path of current from the source: does it go through R3 first and then split, or split before R3? • When current reaches R1 and R2 in figure B, does it have more than one path to return to the source? What does that tell you about series vs parallel? • After you find the equivalent resistance of the R1–R2 section, how do you combine that value with R3 to get the total resistance?

✅ Before You Answer

• Confirm that R1 and R2 share both connection points (top and bottom nodes) to be sure they are truly in parallel • Double‑check your parallel calculation using 1/R_total = 1/10 + 1/10 before inverting • Add the resistance of R3 only once and only after you have found the equivalent resistance of the R1–R2 network
