3 Volt Filament Lamp Graph

Voltage current graph.
3 volt filament lamp graph. The current flowing through a filament lamp is not directly proportional to the voltage. This is the graph of current against potential difference for a filament lamp. Voltage current graph.
V 1 i 0 2 r v i 1 0 2 5 ohm. Country volt is 230 240 volts. Remember that we can calculate resistance r by using r v i.
Making a floor lamp from scratch. Filament lamp for a filament lamp however the temperature of the filament is most definitely not constant it must to get hot in order to give out light the resistance of a lamp s filament the long thin coiled wire increases dramatically as the current increases. You can show that the resistance has changed by reading values of current and voltage from the graph.
