Laboratory investigation into resistance filament bulb

laboratory investigation into resistance filament bulb Thus, a 120-watt bulb must have a thicker filament than a 60-watt bulb (assuming the lengths of the filaments are identical) 2 calculate the resistance and the current of a 75-watt night light bulb plugged into a us household outlet (120 v.

C calculate the resistance of the lamp at its running temperature d now, for several different values of pd, measure the current through the lamp plot a graph of your results this graph is known as the voltage-current characteristic of the lamp. Hh723 the filament tester to investigate a variety of elemental filament materials to discover the materials-property relationships needed for enhanced filament and light-bulb performance. When a light bulb filament is glowing white hot, its resistance is much greater than when it is cool resistors can be combined in series or in parallel the total resistance of several resistors in series is just the sum of the individual resistances. A laboratory investigation on the impact resistance of a woven geotextile staple fiber and continuous filament it was reported that greater puncture resistance was observed in staple fiber geotextiles the chamber was placed into a pit in the laboratory prior to testing, various fixing techniques for geotextile at the periphery of.

Laboratory investigation into the resistance of a filament bulb filed under: essays tagged with: data the slope of these three lines gives 3 different resistance values for the filament bulb the resistance of the bulb increases as the current through the bulb increases. Laboratory investigation into the resistance of a filament bulb essay 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. Unit 1 lab report: resistance of wire investigation “to reduce resistance can dramatically reduce the amount of wasted energy of applying electrons into the circuit this led to an increase in the resistance of the filament bulb moreover, there was no increase in the wire resistance, but there was an.

- an investigation into the effect of an electric current on copper sulphate solution aim in this experiment my aim is to enforce and develop ideas about the investigation into the effect of an electrical current through copper sulphate solution the resistance is greater when the light bulb is hotter, because when electrons getting. - 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. See how the equation form of ohm's law relates to a simple circuit adjust the voltage and resistance, and see the current change according to ohm's law predict how current will change when resistance of the circuit is fixed and voltage is varied predict how current will change when voltage of the. Laboratory investigation into the resistance of a filament bulb 5/2/2006aim: does the resistance of a filament bulb change as the bulb gets brighterhypothesis: i believe that a filament bulb will have.

The resistance is greater when the light bulb is hotter, because when any material is heated, the atoms making up that material vibrate over a larger distance more than they usually do though the reason that the filament in the light bulb heats up and glows is because the electrons passing by at a normal speed will still knock into atoms. Battery and into the bulb (b) two current probes, one connected as in (a) and the other resistance of a light bulb changes as it heats up, quickly reaching a 28 lab 2 - batteries, bulbs, & current university of virginia physics department modified from p laws, d sokoloff, r thornton. Laboratory investigation into the resistance of a filament bulb 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. Laboratory investigation into the resistance of a filament bulb essay sample 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.

The stefan boltzmann law our source is a light bulb with a tungsten filament there is really nothing special about this light bulb -- in fact, it is a common automotive headlight bulb -- but it calculate the filament resistance the ratio of that resistance to room temperature resistance (r300) is the indicator of filament temperature. A flashlight that is powered by 3 volts and uses a bulb with a resistance of 60 ω will have a current of 005 amps 8 use the ohm's law equation to determine the missing values in the following circuits. Simulation experiment where you change the voltage across a filament bulb and psi physics ap 1 – electric current see how the equation form of ohm's law relates to a simple circuit its practical applications are perhaps infinite and extend from small lab circuits to rocket and control systems. Lab exercises a investigation 1: what is needed to light a bulb b investigation 2: is anything happening in the wires comparing resistance of bulbs and wires c investigation 3: resistance of bulb combinations 2 summary exercises (section 2) obtain a ‘dissected’ bulb from the teacher the filament is very delicate so work.

Laboratory investigation into the resistance of a filament bulb 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. For example, the filament in a light bulb and a toaster have a high resistance there are four factors which influence the amount of resistance of a conductor: type of material, length, thickness and temperature. Some of them [24] [25] [26] used a measurement setup equipped with a lamp consisting of a light bulb with a tungsten filament, whose resistance r is measured for various values of electric power. Test the resistance of 40 watt bulb number 1 by holding a multimeter probe to the metal screw part, and the other probe to the metal pin at the base of the bulb record this resistance repeat procedure of the same light bulb with the second multimeter.

Laboratory investigation into the resistance of a filament bulb custom essay help. (c) using information from part (b)(iv), explain why the change in resistance of the filament is less for a current change of 0 to 10 a than for a current change of 10 a to 20 a do not attempt any calculation. Use the magnifying glass to inspect the bulb identify the filament and see how it is connected to the base of the bulb screw the bulb back into the socket and construct the circuit shown in figure 1 below connect so the resistance of the bulb, under these conditions, is about 36.
