A voltmeter and an ammeter are implemented into the circuit, the voltmeters job is to make measure the electric potential difference and the ammeters job is to measure the current in the circuit. These combined or separately can provide the data neededThe results from this could be recorded down and made into a graph if needed. ( 5 marks ) c The current–potential difference graph below shows the relationship between the current and potential difference for a resistor. Graph 1 i State the current flowing when the potential difference across the component is 2 V. 0.2 A ( 1 mark ) © Oxford University Press 2016 This resource sheet may have been changed from the original. 2 Variable resistor voltmeter cell P3.2.4

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
