Electrical Properties of a filament lamp Aim- to discover whether a filament lamp is an ohmic conductor. Apparatus- to follow through this experiment I will use the following equipment: * A 12 Volt power supply * The ammeter setting on one digital multi-meter * The voltmeter setting on another digital multi-meter * A variable resistor used to vary the voltage from roughly 2V to 11V. This will be finalised from my preliminary experiment. * A tungsten filament light bulb * Wires Method- below is the method I will use to discover whether the filament lamp follows ohms law: * Construct the below circuit, one digital multi-meter set to voltmeter in parallel, and one digital multi-meter set to ammeter in series. * Move the slider on the variable resistor up in stages to vary the voltage reading from 2V to 11V * Take note of the ammeter reading in a table. Repeat this at least two times for accuracy and check that...
