Filament Bulb Investigation How the resistance of a filament bulb varies its current flowing through it? Aim: the purpose of this investigation is to find out how the resistance of a filament bulb varies with current flowing through it. Hypothesis: I think the higher the voltage the brighter the bulb will be because then there will be an increase of current and the electrons are given more energy and more are forced through, therefore the bulb would be able to resist more. If the voltage increases the bulb will shine bright because the bulb would have more energy. Controlled Variable- the controlled variable for this experiment is number of bulbs because the decision is for me to make. Independent Variable- the independent variable for this experiment are the volts, I will be using 1-12v. Independent Variable- The independent variable would be the reading we get of the ammeter. Apparatus- * 5 wires *...
