Make sure you are familiar with the characteristic graphs of the filament lamp and the thermistor. Surge current protection. 1. Sketch graphs of current vs. potential difference for a filament lamp rated 230 V; 25 W. Explain the shape of the graph in terms of the effect of temperature on the conductance / resistance of the lamp.

WebThis is because: As the current increases, the temperature of the filament in the lamp increases. Since the filament is a metal, the higher temperature causes an increase in resistance. Resistance opposes the current, causing the current to increase at a slower rate. Where the graph is a straight line, the resistance is constant. WebTaking corresponding pairs of values for V and I from the graph at different voltages will give different values of resistance. The resistance will be higher at higher voltages. The …
