| 1 | There is a capacitor in there. | |
| 2 | The other pole of the capacitor is grounded. | |
| 3 | This would enable wearable capacitors to be made economically, he reckons. | |
| 4 | The resistor and the capacitor together were the timer, and the transistor worked as the switch. | |
| 5 | Part of this process involves applying an electric field to a dielectric material within the capacitor. |
