T2* can be considered an observed or effective T2, whereas the first T2 can be considered the natural or true T2 of the tissue being imaged. T2* is always less than or equal to T2. T2* results principally from inhomogeneities in the main magnetic field.These inhomogeneities may be the result of intrinsic defects in the magnet itself or from susceptibility-induced field distortions produced by the tissue or other materials placed within the field.2* can be considered an observed or effective T2, whereas the first T2 can be considered the natural or true T2 of the tissue being imaged.

The average electricity consumption of a US family of four is in the neighborhood of 50 kWh per day, or 1,500 kWh per month. Similar figures apply for Canada. Assuming an average electricity cost of $0.12 per kWh, that translates into about $6 per day for electricity, or $180 per month.
This says the average USA household uses 908 kwh a month. If the average household is 3 people, then that is 908 kwmh / 30 days / 3 people = 10 kwh per person per day.That sounds more believable.elevance. Rating Newest Oldest.

According to the above link, the average person in USA uses 1,460 watts of power So that means if they use it for 24 hours a day it would be 1460watts * 24 hr = 35040 watt hr / 1000watts = 35 kWh a day per person.
