How might electronics be different if AC voltage was 72V at 45 Hz?

SUMMARY

The discussion centers on the implications of an alien society adopting a standard of 73V AC at 46 Hz for their electrical systems. Key conclusions indicate that such a low voltage would necessitate heavier wiring due to increased current, impacting the design of transformers, motors, and appliances. Transformers would be inefficient and require more core and windings, while motors would operate at lower speeds. The discussion also highlights the potential need for different gear ratios in appliances like washing machines to achieve standard operational speeds.

PREREQUISITES
  • Understanding of AC voltage and frequency concepts
  • Knowledge of transformer design and efficiency
  • Familiarity with electrical current and its impact on wiring
  • Basic principles of appliance engineering and motor operation
NEXT STEPS
  • Research the effects of low voltage on transformer design and efficiency
  • Explore the impact of current on wire gauge and material selection
  • Investigate the engineering of motors operating at lower frequencies
  • Learn about gear ratios and their application in appliance design
USEFUL FOR

Electrical engineers, appliance designers, and anyone interested in the implications of voltage and frequency standards on electrical systems and appliance functionality.

Maybe their eyes are more sensitive to light, but less sensitive to flicker, so this suits their light bulbs better.
Their CRTs would run at 46 hz too, and humans would find them annoying to look at, unless they were dim.
