A circuit is used to obtain the I–V graph of a diode. The diode is connected in series with a variable resistor and a cell. Where should the voltmeter be connected to measure the potential difference for the graph?
- In parallel across the diode only
- In series with the diode
- Across the cell and variable resistor together
- In parallel across the variable resistor only
