The current flowing through a filament lamp is not directly proportional to the voltage.
Voltage vs current graph for filament lamp. Resistance of the filament lamp increase with temperature. As the potential difference across a filament lamp increases the current increases and the energy dissipated as heat increases resulting in a higher temperature. Voltage current graph. This is a messy question to answer because the resistance depends also on time.
As the temperature increases resistance of the filament increases. This is the graph of current against potential difference for a filament lamp. Endgroup jaime jan 7 13 at 7 38. You need to know how to investigate how current changes with voltage for a component eg for a resistor or wire at constant temperature a filament lamp and a diode.
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. From the i v graph the ratio v i increases as current increases. A diode a diode only allows current to flow in one direction through it forward biased when the current tries to flow the other way reverse biased no current is allowed to flow through the diode. I am afraid you are going to have to go with your graphs.
