1. Passo 1. Power line — tem como parte — Fio de cobre. Wires (often aluminium).
2. Passo 2. Fio de cobre — faz parte de — Inductor. A winding.
3. Passo 3. Inductor — faz parte de — Oscillator. An LC circuit.
4. Passo 4. Oscillator — faz parte de — Relógio atômico. A quartz oscillator is tuned to the atoms.
5. Passo 5. Relógio atômico — evoluiu de — Quartz clock. The quartz oscillator is tuned to an atomic standard.
6. Passo 6. Quartz clock — evoluiu de — Mechanical clock. Quartz clocks replaced mechanical ones: a vibrating quartz crystal took the place of the pendulum and balance.
