Capacitance and oil lamp: what they have in common

1. Step 1. Capacitance — is used in — Microphone. In a smartphone’s MEMS microphone, the vibrations of the diaphragm change the capacitance between it and a fixed plate.
2. Step 2. Microphone — uses — Piezoelectric effect. Piezo microphones turn sound pressure into voltage.
3. Step 3. Piezoelectric effect — is used in — Lighter. Piezo lighters.
4. Step 4. Lighter — has part — Wick. Petrol lighters have a wick.
5. Step 5. Wick — is part of — Oil lamp. The wick feeds oil to the flame.
