Investigating electrical behaviour and a filament lamp. Aim: My aim in this investigation is to find electrical behaviour of a resistor and a filament lamp. Planning: Apparatus: Below are the following equipment used throughout the experiment: * Resistor * Filament Lamp * Ammetre * Voltmetre * Power Supply * 5 wires Diagram: Prediction: I predict that for the filament lamp as soon as the voltage increases, so will the resistance. This is because the filament gives out light, when the temperature of filament is increased. The filament lamp gives out heat because an electric current is passing through the components lamp. As the filament increases in temperature, the particles start to vibrate more. The vibration causes difficulty for the electrons to pass through. I assume that the filament may need a certain amount of electricity / energy before it can give any heat or light out. The filament lamp needs to be at a certain temperature in order the lamp can...
