5/2/2006 Aim: Does the resistance of a filament bulb change as the bulb gets brighter? Hypothesis: I believe that a filament bulb will have an increasing resistance depending upon the current passing through it. Equipment: *Power Supply *Wires *Ammeter *Voltmeter *Filament bulb with holder *Alligator clips *Switch Method: 1.Set up the circuit according to the schematic diagram 2.Use the alligator clips to connect the filament bulb to the voltmeter 3.Connect the power supply to the electricity

to analyze the input and output signals produced by the amplifier. Because of the resulting output signals‚ which will be discussed further in other sections‚ this amplifier is essential to AC appliances requiring a certain amount of voltage and current gains. II. METHODOLOGY A. Materials and Equipment To construct the circuit‚ the electronic devices needed are as follows: capacitors of values 0.33 uF and 0.47uF‚ resistors of values 56k‚ 5.6k‚ 680 and 6.8k‚ a 2N3904 NPN transistor.

Investigating the current - potential difference relationship for a metal wire. Aim: To design an experiment that will facilitate an I - V Graph to be ascertained of a metal wire and thus find the resistance of the wire by deriving the inverse of the gradient of the graph. Skill: Planning & Designing Theory: Resistance is a property of any object or substance to resist or oppose the flow of an electrical current. The quantity of resistance in an electric circuit determines the amount of current flowing in
