Solution to task 377 from Chertov´s for extramural stud

377. During the time t = 8 s with a uniformly increasing current strength in the conductor with resistance R = 8 Ohm, the amount of heat Q = 500 J. Determine the charge q passing in the conductor if the current strength at the initial moment of time is zero.
