What is Investigating Current-Voltage Relationships about?

A student is setting up a circuit to investigate how the current varies with voltage in different circuit components including a short thick copper wire, a filament lamp, a long thin copper wire, and a diode. The student needs an ammeter, a voltmeter, a power supply, and switches to complete the circuit and measure current and voltage. The student keeps the copper wires at a constant temperature during testing to prevent temperature changes from affecting the measurements. The student could use a temperatur
