How does ldr work in a circuit

WebLDR Symbol. The LDR symbol in most circuits is often the resistor circuit symbol. This symbol shows arrows shining on it, representing the light rays. The hands resemble that … WebThe resistor (10k) does limit the maximum current that flows through the LDR but its function is to to provide a voltage signal. Your second circuit without a ground (0V) connected the input (which takes very little current) means that the input would only see the 5V (Vcc) even when the resistance of the LDR changes between its extremes.
