Investigating the relationship between voltage, current and resistance


The component, the ammeter and the variable resistor are all in series, which means they can be put in any order in the main circuit. The voltmeter, on the other hand, can only be placed in parallel around the component under test. It is not allowed anywhere else.

As you vary the variable resistor, it alters the current flowing through the circuit.

This allows you to take several pairs of…
