A student sets up a circuit with a power supply, a resistor, and a voltmeter.
Where must the voltmeter be connected, and what does it measure?
in series with the resistor to measure the current through the resistor
in parallel with the resistor to measure the current through the resistor
in series with the resistor to measure the potential difference across the resistor
in parallel with the resistor to measure the potential difference across the resistor
