The collector feedback circuit maintains a relatively stable Q point than the other biasing methods. Evaluate the statement.
A dielectric interface is defined by 4x + 3y = 10. The region including the origin is free space, where D1 = 2ax – 4ay + 6.5az nC/m^2. In the other region, epsilon r2 = 2.5. Find D2 and the angle (theta)2 that D2 makes with the normal.
