LED Transistor switch with delay

This circuit is a transistor switch with an RC delay. When the switch is closed, current flows into the base through the resistor, turning the transistor on and lighting the LED. At the same time, the capacitor charges. When the switch is open, the capacitor slowly discharges through the base, keeping the transistor on for a short period before it turns off. This creates a brief delay where the LED stays on after the input is removed, demonstrating how capacitors can be used for timing in simple control circuits.
