Circuit diagram with an ideal voltmeter connected in series.
A student attempts to construct a circuit to measure the current and potential difference associated with a resistor of resistance \(R\) connected across an ideal battery of electromotive force \(\mathcal{E}\). However, the student mistakenly connects an ideal voltmeter in series with the resistor and battery. Which of the following correctly gives the electric current \(I\) in the circuit and the potential difference \(V_V\) measured by the voltmeter?
