The first capacitor whose capacitance C1 = 1 uF capacitors charged to a potential difference the U1 = 5 V, and the second, the capacity of which C2 = 0.5 uF, to the difference between the potentials U2 = 20 V. Then, the capacitors connected to the power and connected to each other the same sign charged plates. Find: The number of heat released when connected capacitors; volumetric energy density of the electric field in the second flat capacitor (d2 = 5 mm; e2 = 10) after connection of capacitors.
