AN INVESTIGATION TO SHOW HOWTHE VOLTAGE AFFECTS THE CURRENT IN A LIGHTBULB Aim:~ An investigation to show how the voltage affects the current flowing through a light bulb. Hypothesis:~ I predict that as the current increases the voltage of the lamp will also increase; thus causing the resitance to decrease. I think this because of Ohm's Law which states that current will increase in proportion to voltage; if the current is doubled the voltage is also doubled. Bearing this in mind my graph should resemble my diagram below: X X X X X X X X If the voltage across a light bulb is increased, more current will flow through it. If the number of bulbs in a series circuit is increased, less current will flow through them. The lamps resist the current, so if you put more lamps into the circuit there is more resistance. As the resistance of the...
