The Relationship between the number of bulbs in a circuit and the size of the current Aim: To investigate the relationship between the number of bulbs in a circuit, and the size of the current. Prediction: I believe that the more bulbs in a circuit the less current there will be. Theory: I expect that the more bulbs the less current because in a wire all the ions are in a crystal lattice, between each ions there are bonding electrons which join each ion to another. In the space around the ions there are free electrons, these free electrons are what create the current in a circuit. Once there is a complete circuit with a cell or battery the free electrons in an organised pattern follow the electromotive force which is created by the cell/battery. Once the current meets with the filament in the bulb there is a lot of friction created. In a...
