A capacitance touch lamp works by detecting the tiny changes in electrical charge that occur when you touch its metal surface. The lamp’s body is connected to an electronic circuit that constantly monitors its capacitance - the ability to store a small amount of electric charge. When you touch the lamp, your body (which conducts electricity) acts like a capacitor plate and adds extra capacitance to the circuit. The lamp senses this sudden change and sends a signal to the control circuit, which switches the light on, off, or cycles through brightness levels. This means the lamp doesn’t need a physical switch - your finger’s natural electrical properties are enough to control it.#science #physics #electronics #facts
