Answer: Parallel.
- A Parallel
- B Series
- C Either way
- D Between batteries
Correct answer: A. Parallel
Explanation: Voltmeter measures voltage (potential difference) and must be connected in parallel across the component.
In series, the same current flows through both resistors; in parallel, the current splits between branches and the voltage across each resistor is the same.
