🔍 Key Concepts

• Identify from figure A which resistors are in series and which are in parallel • Use the rule for equivalent resistance of series and parallel combinations • Apply Ohm’s Law ( I = \frac{E}{R} ) with the source voltage of 24 V

💭 Think About

• From the negative side of the source in figure A, trace the current path and note where the path splits and where it rejoins. Which resistors share the same current, and which share the same voltage? • Once you know which resistors are in series, add their resistances. Then, if that group is in parallel with another resistor, how do you combine them into one equivalent resistance? • After finding the single equivalent resistance for the whole network, how do you use 24 V and that resistance to find the total circuit current?

✅ Before You Answer

• Be sure you correctly classify R1, R2, and R3 as series vs parallel based on the drawing, not just their positions on the page • Double‑check your equivalent resistance calculation (especially the parallel step) before using Ohm’s Law • Confirm that your final current uses the total equivalent resistance of the entire network, not just one branch
