T2 * relaxation refers to the decay of transverse magnetization seen with gradient-echo (GRE) sequences. T2 * relaxation is one of the main determinants of image contrast with GRE sequences and forms the basis for many magnetic resonance (MR) applications.2 * is shorter than T2 (Fig 1), and their relationship can be expressed by the following equation (3), where Î³ is the gyromagnetic ratio: 1/T2 * = 1/T2 + Î³ Î´B inhom, or 1/T2 * = 1/T2 + 1/T2â², where 1/T2â² = Î³ Î´B inhom, and Î´B inhom is the magnetic field inhomogeneity across a voxel.
Simpler answer: Energy used per day is measured in watt-hours, or more usually kilowatt-hours, and a typical house might use 35 kilowatt-hours per day. That is equal to 1.458 kilowatt-hours per hour, in other words an average power of 1.458 kilowatts.
Best Answer: The average household in America consumes 10,656 kilowatt-hours (kWh) per year, according to the Department of Energy. Dividing that by 365 gives about 29. But that is just an average.
