🔍 Key Concepts

• Series circuit in Figure B – does the current have more than one path, or only one? • Total resistance in series – how do you combine R1, R2, and R3 when they are in series? • Ohm’s Law: I = V / R – relate the 24‑volt source to the total resistance you found.

💭 Think About

• Look closely at Figure B: when the switch is closed, does the current pass through R1, R2, and R3 one after another, or are any of them in parallel? • Once you know the configuration, write a single value for the total resistance, then use Ohm’s Law to compute the circuit current. • After you calculate the current, compare your result with the multiple‑choice answers and see which one matches exactly.

✅ Before You Answer

• Be sure you add the resistances only if you are certain they are in series all the way around the loop. • Double‑check your total resistance calculation before dividing the voltage by resistance. • Confirm your final current value’s units (amps) and make sure it is reasonable for 24 volts across that amount of resistance.
