WebSet up a circuit with a cell, an ammeter, variable resistor and a filament lamp in series. Attach a voltmeter in parallel across the filament lamp. In the experiment, we need to ensure that the temperature stays constant. Alter the current. Change the current in the circuit by moving the variable resistor. WebThe Light-Dependent Resistor (LDR) In a light-dependent resistor the resistance decreases as the light intensity (brightness of light) increases. At low light levels or in the dark the resistance of an LDR is high and little current flows through it. In bright light the resistance of an LDR is low and more current flows through it. WebA light-dependent resistor (LDR) is a non-ohmic conductor. It is represented by the following circuit symbol: LDR circuit symbol. The resistance of an LDR changes depending on the … t table alpha
