🔍 Key Concepts

• Recognize from the figure whether R1, R2, and R3 are in series or parallel in diagram B • Use Ohm’s Law to find circuit current: I = V / R_total • Use a power formula for a single resistor: P = I^2 · R, P = V · I, or P = V^2 / R

💭 Think About

• From the diagram, trace the path of current starting at the source Es and note the order in which it passes through R3, R2, and R1—are there any branch points? • Once you know the total resistance, how do you compute the same current that flows through each resistor in a series circuit? • After finding the current, which power formula is easiest to apply directly to R2 using its resistance value?

✅ Before You Answer

• Confirm that the total resistance is the simple sum of R1, R2, and R3 (only if they are indeed in series). • Double-check the circuit current calculation using the applied 24 V and the total resistance before moving on. • When computing power in R2, be sure you are using only R2’s resistance with the correct current through it, not the total resistance.
