What is the voltage across the capacitor?
When the circuit is powered, the capacitor starts to charge through the resistor. As the capacitor charges, the voltage across it increases until it reaches a certain threshold. Once this threshold is reached, the capacitor discharges through the resistor, causing the voltage to drop. This cycle repeats, causing the lamp to flash on and off.
