in japan, there is no standard AC frequency. as a result, there are two national grids. also, Japan is the only country using 100V voltage
>>
And somehow their CRTs still were 60hz even in the 50hz regions. What gives?

nothing surprising

CRTs depend on broadcasting standards, them matching the AC frequency makes some parts of their design slightly easier but it's not necessary. Japan just adopted America's standard nation-wide. Practically all CRTs past a certain point were able to switch between 50Hz and 60Hz regardless of the power frequency.

>using less power to accomplish the same job makes you a backwards shithole
Don't you have to refuel your gasoline powered television or something?

>using less power to accomplish the same job
explain the logic behind this statement
>>
>>107567287
voltage != power

This is wrong.
There are two standards.
>>
There are five grids in US/Canada. So what?
>>
>>107566933
I still remember when japan was occupied by germany (north) and the USA (south). So many causalities at the second border war.

now days it doesn't matter.

In the very early days, TV was matched to line frequency for performance reasons. It was not actually a hard requirement. And as electronics got better this synchronization became less important. When color game out, TV was uncoupled from line rate. Also, Japan TV broadcast apparently started in 1953, so it totally skipped the early TV era where synchronization mattered.

for the life of me I can't understand the difference between wattage, voltage or amperage, how they relate and what they're used for. most explanations are surface level babyshit and I don't get it because I don't see the bigger picture.
I somehow got a job in electrical infrastructure but I don't know shit!

Voltage is like the diameter of a pipe, amperage is the amount of water flowing through it, and wattage is if you take that diameter and multiply it by the amount of water flowing through it.
