What powers are dissipated by the diodes marked in the figure’s circuit? Assume that the current of the diodes is zero for all the reverse voltages and also for forward voltages below one volt. For a random forward voltage the voltage of the diode is 1,0 V. The values of resistors’ resistances and the electromotive force are marked in the drawing. The direction of a diode’s arrow in the drawing shows the direction of the forward voltage.
