Robert Cinca - Physics Part 2: Testing the Filament Bulb Part 2: Testing the Filament I tested the hypothesis of the current from the earlier Bulb logical argument using Part 2: surge Testing the Filament Bulb two different filament bulbs 0.15A and 0.30A). Bulb Part (6.5V 2: Testing the 6.5V Filament I In hypothesis the current logical using order the to measure the of current time, from I first the set earlier up a potential divider circuit I tested tested the hypothesis of surge the surge surge current from the earlier logical argument argument using (as two filament bulbs 0.15A and 6.5V 0.30A). I in tested the 2) hypothesis the surge current earlier logical argument using shown figure two different different filament bulbs of (6.5V (6.5V 0.15A and from 6.5V the 0.30A). two different filament bulbs (6.5V 0.15A and 6.5V 0.30A). In to the surge current time, I I first set up potential divider circuit (as In order order to measure measure the the surge current time, first set up up a a a potential potential divider circuit (as In order to measure surge current time, I first set divider circuit (as DC Power Pack shown in figure 2) shown in figure 2) shown in figure 2) DC Pack Power Pack DC Power DC Power Pack Variable Resistor Data Studio Variable Resistor Resistor Variable Variable Resistor Filament Bulb Data Studio Data Studio Data Studio Filament Bulb Filament Bulb Filament Bulb GLX Data Logger GLX Data Logger GLX Data Logger GLX Data Logger Figure 2: Setting up my experiment Figure 2: Setting up my experiment The equipment used used was was as as follows: The equipment follows: Figure 2: Setting up my experiment Figure 2: Setting up my experiment  filament two filament bulbs (6.5V 0.15A and and 6.5V 6.5V 0.30A)  two bulbs (6.5V 0.15A 0.30A)  a variable resistor The was a variable used resistor The  equipment equipment used was as as follows: follows:  a powerpack (e.m.f. supply)  a powerpack (e.m.f. supply)  filament a GLX data logger (voltmeter+ammeter)   two bulbs 0.15A two filament bulbs (6.5V (6.5V 0.15A and and 6.5V 6.5V 0.30A) 0.30A) a GLX data logger (voltmeter+ammeter)  data studio (computer software)   a variable resistor a variable data studio resistor (computer software)   In a powerpack (e.m.f. supply) experiment, the ammeter a my powerpack (e.m.f. supply) and voltmeter were part of the GLX data logger, a   experiment, a GLX data logger (voltmeter+ammeter) In my the ammeter and voltmeter were them part so of they the can GLX a device used to record measurements and process be data read logger, by a GLX data logger (voltmeter+ammeter) I used software) data studio as a computer program in order to record all   computer data (computer device used studio to software. record measurements data studio (computer software) and process them so they can be read by my results. computer software.
