To Measure the Potential Difference Across a Resistor in an Electric

Multiple Choice

To measure the potential difference across a resistor in an electric circuit, a voltmeter should be connected

A) in parallel with the resistor.
B) in series with the resistor.
C) either in parallel or in series with the resistor, depending on the geometry of the circuit.
D) neither in parallel nor in series with the resistor because the potential difference cannot be measured with a voltmeter.
