Power, defined as P = dE/dt is Lorentz invariant according to
http://farside.ph.utexas.edu/teaching/em/lectures/node130.html, Eq. 1645
But, considering another equation for the power, P = q E v, where E and v are electric field and velocity vectors, respectively; this is obviously not the case since in the momentarily rest frame of the charge P = 0?
What is wrong with the above reasoning?
Thanks!
