Is the peak energy stored in the circuit divided by the average energy dissipated in it per cycle at resonance, and is the inverse of fractional bandwidth

In physics, intensity is the power transferred per unit area, where the area is measured on the plane perpendicular to the direction of propagation of the ... more

The Stefan–Boltzmann law, also known as Stefan’s law, describes the power radiated from a black body in terms of its temperature. Specifically, the ... more
