Today, someone from the electricity company came to check the meter. Does anyone know why there's a spinning disc inside? I mean, these days everything is digital, why can't the meter be digital as well?
where am I ?
It seems that you are talking about an mechanical electricity meter , in which case the disk is like a wheel which operates the all meter and the electricity make the wheel turn. A lot of electricity makes it turn fast a little makes it turn slow.
So some place do use digital meters?
They are just now within last few years changing over to electronic meters but Im not sure how they determine who gets one. Also when you are using electricity it turns the dial, the more power consumption the faster it turns which determines your utility bill. It has hidden gears behind the front platewhich are rotated by the large disc and they have a needle on them that points to a specific number and thats how your bill is calculated. It works a lot like a grandfather clock.
