The LED bulb has a capacitor on the chip with a capacity of 4.7 µF and a resistor with a resistance of 100 kΩ. Turn off the light bulb. After approximately how long will the capacitor be empty and the circuits on the chip allowed to be touched? State the procedure and describe how the voltage across the capacitor changes over time. Assume that after turning off the bulb, negligible currents flow through the remaining parts of the circuit (the bubble in the picture).
