CHECKPOINT #3 7 DATA ANALYSIS TASK Measuring Voltage A group of students conducted an experiment using resistors and a \"\"- voltmeter. They were provided with a selection of resistors with resistances of 100 Q, 220 O and 3300, a 3V battery, connecting wires and a digital \"\"- voltmeter They were also provided with a resistor whose value was not known. The resistors they were given were labelled as follows. X is the resistor with the unknown resistance. Below is Abi and Mark's write up. We set up the four circuits shown in the diagrams. For each circuit we measured the voltage across the battery, and the voltage across each resistor separately. Our results are shown below. The battery voltage was 3.0 V in every case. voltagetw resistor Voltage (V) Voltage (V) A _E- [- Ii- 2-30 l-I Q10. What do you think Abi and Marks research question was?
