Another example of nonlinear current conduction is through gases such as air. At standard temperatures and pressures, air is an effective insulator. However, if the voltage between two conductors separated by an air gap is increased greatly ...
WebThe IV graph for a filament lamp shows the current increasing at a proportionally slower rate than the potential difference. IV graph for a filament lamp. This is because: As the current increases, the temperature of the filament in the lamp increases. The higher temperature causes the atoms in the metal lattice of the filament to vibrate more. WebNov 15, 2010 · PTC type thermistors’ resistance increases as temperature increases. Metals have positive temperature coefficients. Important: Gradient of I-V curve is not equal to the resistance of the component. …
