14. 如圖 11 所示之理想變壓器電路，試求其等效電阻 R= ______Ω 。

1. (15 points) Three spherical conductors of diameters (直径) \( d{1}, d{2} \), and \( d_{3} \) are separated by distances much greater than the radius of each sphere. The spheres are connected by a conducting wire as shown in Figure 1. Assume each of the three spheres is uniformly charged in electrostatic equilibrium. The total charges of the three spheres are \( Q \) Coulombs. Find the charge density (6 points), the electric potential (3 points), and the magnitude of electric field (6 points) on the surface of each of the spherical conductors.
