- Step 1. Transistor — is part of — Hi-fi amplifier. Amplification comes from transistors or tubes.
- Step 2. Hi-fi amplifier — has part — Transformer. The power supply is a transformer.
- Step 3. Transformer — is part of — Nuclear power plant. Transformers step up the voltage so the plant's power can travel far.
- Step 4. Nuclear power plant — has part — Steam turbine. Steam turns the turbines — as at a thermal station.
