How a filament light bulb effects current and voltage Prediction: My prediction is that the first experiment I will do which is the fixed resistor will follow ohms laws correctly. In the second experiment I will change the fixed resistor with a filament light bulb, this experiment will not follow the rules of ohms law. Back ground information: States that the steady electrical current in a metallic circuit is directly proportional to the constant total electromotive force in the circuit. If a current I flows between two points in a conductor across which the potential difference (voltage) is E, then E/I is a constant (which is know as the resistance, r, between the two points). Hence E/I=r. Equations relating E, I and R are often quoted as ohm's law, but the term 'resistance' did not enter into the law as originally stated. From the Hutchinson Encyclopedia. Equipment list: The equipment I used were these: •Power...
