A student sets up a circuit to determine the resistance of a fixed resistor. Which row in the table correctly describes how the ammeter and the voltmeter must be connected to measure the current through and the potential difference across the resistor?
| Ammeter connection | Voltmeter connection | |
|---|---|---|
| A | in parallel with the resistor | in parallel with the resistor |
| B | in parallel with the resistor | in series with the resistor |
| C | in series with the resistor | in parallel with the resistor |
| D | in series with the resistor | in series with the resistor |
