WebApr 12, 2024 · Power regulator circuits, both linear and switching regulators, include feedback loops as mechanisms to ensure the circuit outputs at a target voltage. These feedback loops play a simple but important role in power regulator circuits: they dynamically adjust the output voltage so that the target value is always reached. 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. flower tutorial drawing
