Задача id16228

Two parallel metal plates are connected to a voltage source with emf E (Fig. a). In parallel, two more metal plates are introduced, so that the distance between each of the plates is equal to d. 1) Determine the potential of each of the four plates and the field in all three spaces between the plates. 2) How will the plate potentials and field strengths in all gaps change if plates 2 and 3 are short-circuited? 3) How will the charges on plates 1 and 4 change? 4) Will plates 2 and 3 be charged before and after the circuit?
