Which of the following statements is correct...

🔍 Key Concepts

• Series vs. parallel circuits – look for branches or separate current paths in figure B. • In a series circuit, current is the same through all components and the total resistance is the sum of the resistors. • In a parallel circuit, voltage is the same across all branches and the reciprocal formula 1/Rt = 1/R1 + 1/R2 + 1/R3 applies.

💭 Think About

• Trace the path of current from the source Es in figure B: does it ever split into more than one path before returning to the source? • If you placed a voltmeter across each resistor (R1, R2, R3), would each meter be connected to the same two nodes, or to different points along the loop? • Think about which formula for total resistance would make sense based on whether there is only one path for current or multiple paths.

✅ Before You Answer

• Verify whether there are any junctions or branch points in the circuit where current could divide; this determines series vs parallel. • Check if each resistor shares the exact same two connection points (nodes). If yes, they’re parallel; if not, they’re in series along the path. • Confirm which statement about total resistance matches a single‑path (series) circuit and which matches a multi‑path (parallel) circuit.
