No, 200 watts is not a measure of electricity consumed per hour, but rather a unit of power. To determine the electricity consumed per hour, you would need to know the duration the power is being used. If an appliance consumes 200 watts per hour, it's relatively low power consumption compared to appliances like air conditioners or heaters.
The power consumption of an AC unit can vary depending on factors like size, efficiency, and usage. On average, a window AC unit can consume anywhere from 500 to 1500 watts per hour, while a central AC system can consume around 3000 to 5000 watts per hour. To calculate exact power consumption, you can check the unit's specifications or monitor its energy usage with a watt meter.
There are 24 time zones in the world, each representing a one-hour difference in time. However, some regions use half-hour or 45-minute offsets from this standard, resulting in more than 24 distinct time zones.
It is normal time. Most of the world uses the 24 hour clock, rather than the 12 hour clock. As far as the 12 hour clock would go, that would be 4:30 PM. Anything you see over 13:00, just subtract 12, and you'll get the time you would on a 12 hour clock (PM).
