🔍 Key Concepts

• Identify which resistors are in series and which are in parallel in figure B. • Use the equivalent resistance of the circuit to find the total current from the 30‑volt source. • Apply the power formula for the whole circuit: P = V^2 / R_total.

💭 Think About

• Look at how R1 and R2 are connected to each other and then how that combination is connected with R3—are they sharing the same two nodes (parallel) or end‑to‑end (series)? • Once you have the equivalent resistance of R1 and R2, how does adding R3 in series or parallel change the total resistance seen by the source? • After you compute the total resistance, what total power do you get when you plug V = 30 V into P = V^2 / R_total, and which choice is closest?

✅ Before You Answer

• Be sure you combine R1 and R2 correctly as series or parallel before adding R3. • Double‑check your equivalent resistance calculation using the correct formula for parallel resistors: 1/R_eq = 1/R1 + 1/R2 (if they are parallel). • Confirm that your final power value uses volts squared divided by ohms so the units come out as watts.
